AlN – a New Platform for Electronics

Abstract:AlN has been ardently pursued as one of the most promising ultra-wide bandgap semiconductors (UWBGs) after GaN and SiC as the industry has been expanding rapidly on the high-volume manufacturing of GaN and SiC based technologies, including 12-inch GaN-on-Si, 8-inch SiC substrates and processing foundries etc. AlN is CMOS compatible with high thermal conductivity, high acoustic velocity and a rich family of heterostructures. Recently, Sc-, B- and Y-doped AlN alloys have garnered tremendous interest for their ferroelectric behavior. In this talk, I will focus on findings in our journey to develop new electronic devices on AlN in the past two decades.

Wurtzite III-nitrides are well known as a family of polar semiconductors. When sandwiching a narrow gap III-nitride layer with wider gap barrier materials, one interface is characterized as the negative polarization charge interface while the other as the positive polarization charge interface. The polarization charges are fixed in space and emanating electric field while the entire material stack will do everything it can to minimize its total free energy due to the thermodynamic driving force. As a result, compensating charges can be generated: either mobile charge carriers including delocalized electrons and holes, or charged defect states that are localized in the real and energy space. If undesired defect formation is sufficiently suppressed in the heterostructure, mobile charge carriers will be generated and can be harvested for electronic applications. To this end, we succeeded in generating both mobile electrons and holes in thin GaN quantum well sandwiched by AlN. I will discuss how we generate and detect these mobile charges, and some demonstrated utilities in terms of fundamental understanding and practical applications.

Xing received a B.S. in physics from Peking University, M.S. in Material Science from Lehigh University and Ph.D. in Electrical Engineering from University of California, Santa Barbara, respectively. She was a faculty member with the University of Notre Dame from 2004 to 2014. Her research focuses on development of III-V nitrides, 2-D crystals, oxide semiconductors, recently also multiferroics & magnetic materials: growth, electronic and optoelectronic devices, especially the interplay between material properties and device development for high performance devices, including RF/THz devices, tunnel field effect transistors, power electronics, DUV emitters and memories. Together with her colleague Debdeep Jena, they were the first to demonstrate distributed polarization doping (DPD), especially the p-type DPD in nitride semiconductors. This doping scheme is fundamentally different from impurity doping and modulation doping, thus dubbed as the 3rd generation of doping science by Xing. Polarization doping is particularly powerful in polar ultrawide bandgap semiconductors since it might be the only known method to achieve both n-type and p-type in an UWBG semiconductor with doping properties akin to shallow impurity dopants.

Xing has delivered 200+ invited talks and seminars, and has authored/co-authored 350+ journal papers including Nature journals, Physical Review Letters, Applied Physics Letters, Electron Device Letters, and 140+ conference proceeding publications in IEDM, ISPSD etc. Her h-index is 89 on google scholar.

An electrochemical phase-field model for the corrosion of structural alloys by molten saltsModeling and simulation must play a critical role in accelerating the development and qualification of materials for advanced reactors, such as molten salt reactors (MSRs). MSRs are an advanced reactor concept that uses molten salts as either the coolant or both coolant and fuel solvent. However, molten salts can corrode salt facing alloys, introducing corrosion products into the salt that can precipitate in the cold leg of the loop. To evaluate and improve alloy corrosion behavior, we have developed an electrochemical phase-field model for capturing the microstructure-dependent corrosion of structural alloys by molten salts. The model has been applied to the corrosion of nickel-based alloys and stainless steels by molten fluoride and chloride salts. It can represent impurity-limited corrosion in static corrosion experiments and includes the role of activity gradient corrosion with dissimilar alloys for the alloy coupon and salt capsule. We have also applied the model to investigate the impact of pure Ni coatings on the corrosion of Ni-Cr alloys. Working with Drs. Couet and Sridharan, we are adding the impact of radiation to the model. We are also working with them and Dr. Zhang on better understanding the impact of water vapor on corrosion.

Michael R Tonks is the Interim Department Chair and Alumni Professor of Materials Science and Engineering and Nuclear Engineering at the University of Florida. Prior to joining UF in the Fall of 2017, he was an Assistant Professor of Nuclear Engineering at the Pennsylvania State University for two years and a staff scientist in the Fuels Modeling and Simulation Department at Idaho National Laboratory for six years. Prof. Tonks was the original creator of the mesoscale fuel performance tool MARMOT and lead its development for five years. He helped to pioneer the approach taken in the DOE Nuclear Energy Advanced Modeling and Simulation (NEAMS) program to use multiscale modeling and simulation to inform the development of materials models for the BISON fuel performance tool that are based on microstructure rather than burn-up, and he won the NEAMS Excellence Award for that work in 2014. He also won the Presidential Early Career Award for Scientists and Engineers in 2017 and the TMS Brimacombe medal in 2022. His research is focused on using mesoscale modeling and simulation results coupled with experimental data to investigate the co-evolution of microstructure and properties in materials in harsh environments.

MS&E Seminar Series: Cyprian Emeka Uzoh
2025-11-06 13:00 - 14:00
UW-Madison Department of Materials Science and Engineering welcomes Cyprian Emeka Uzoh. His seminar, “Advances in high-performance metallization and packaging for advanced semiconductor applications”, will take place on Thursday, November 6 from 1-2 p.m. in MSE 265.

Bio

Cyprian Emeka Uzoh earned a Bachelor’s degree in Metallurgical Engineering from the University of Wisconsin–Madison in 1978, followed by graduate studies at Rensselaer Polytechnic Institute. He began his career as a research scientist at IBM’s Thomas J. Watson Research Center, where his pioneering contributions to semiconductor metallization laid the groundwork for transformative advances in the field. Following his tenure at IBM, Uzoh continued to drive innovation through leadership roles in several leading technology companies, advancing the development and commercialization of cutting-edge metallization and packaging technologies. His inventions have become the foundation for modern high-performance devices, enabling the scalable fabrication of CPUs, GPUs, high-bandwidth memory, and advanced image sensors used worldwide. In late 1980s and early 1990s his discovery of the bottom-up metal filling process for submicron vias and trenches, along with the demonstration of its scalability to feature sizes below 100nm, would mark a significant advancement in semiconductor manufacturing. These innovations, combined with other Uzoh’s related contributions, enabled the fabrication of lower-cost microchips with both larger and smaller form factors, increased transistor density, and improved electrical performance. The resulting enhancements in interconnect efficiency and reliability have had a lasting impact on the performance and scalability of modern integrated circuits. Uzoh and his colleagues at IBM Research were named “Inventor of the Year 2006” for his discovery of the bottom-up metal filling process and their development of the copper interconnect technology. Uzoh is also a prolific inventor, with 404 Utility patents in the US and more than 750 worldwide.

Abstract

Copper interconnects have become a foundational component in advanced semiconductor manufacturing, serving as critical enablers for high-performance integrated circuits. Their low resistivity, high electromigration resistance, and compatibility with damascene processing have made them indispensable for fabricating leading-edge devices such as GPUs, CPUs, NPUs, high-bandwidth memory (HBM) modules, interposers, and CMOS image sensors. These components are integral to a broad spectrum of systems, ranging from edge devices like IoT nodes and mobile platforms to high-performance computing infrastructure, including data centers and exascale supercomputers. As device scaling continues and interconnect bottlenecks increasingly constrain system performance, the role of copper interconnects in achieving low-latency, high-throughput, and thermally optimized architectures remains critical. This discussion will explore the development and impact of pivotal innovations, including the invention of the proximity plating cell, bottom-up metal deposition in large cavities (ECMD), and the elimination of terminal effects in electroplating, each of which challenged established principles of electrodeposition kinetics. In addition, Uzoh will present in detail his pioneering work in enabling high-density 3D integrated circuits (3D-ICs) and the commercialization of hybrid bonding, a technique that allows for ultra-dense, high-performance chip stacking without the need for adhesive layers.

Sustainability analysis of critical minerals supply chains: attributional and consequential life cycle assessment

By some estimates, more than three billion tons of minerals will be needed to manufacture the decarbonization technologies necessary to limit global warming to 2°C. This demand can be met through increasing production at existing mines, developing new mines, and recovering minerals through recycling of spent devices can also contribute. Life cycle assessment (LCA) is a key analysis tool to evaluate and compare the environmental effects of producing minerals from different sources. This presentation will present recommendations for attributional LCA of minerals mining based on a literature review and apply them in the development of a perspective of a proposed mine in Minnesota. While attributional LCA aims to assign a unique environmental impact to a mineral product, consequential LCA aims to quantify the overall environmental effects from a change in mining activity. We present consequential LCA results that account for global carbon stock changes arising from the construction of new mines to meet mineral demand. Finally, we explore whether water demands for expanding lithium mining in the U.S. can be met, considering changes in water scarcity that climate change will cause, and what restrictions in water supply mean for the possibility of achieving a fully domestic lithium supply. Altogether, these different forms of sustainability analysis can address the advantages and disadvantages of expanding minerals production and help prioritize technologies and strategies that minimize adverse local environmental effects of mining while pursuing materials that are an important part of the solution to the global challenge of climate change. results from both will be discussed.

MS&E Seminar Series: Dr. Saryu Fensin, Los Alamos National Laboratory
2025-11-13 13:00 - 14:00
UW-Madison Department of Materials Science and Engineering welcomes Dr. Saryu Fensin. Her seminar, “SPARK: Accelerating Alloy Discovery with AI and Self-Driving Labs”, will take place on Thursday, November 13 from 1-2 p.m. in MSE 265.

Bio

Dr. Saryu J. Fensin is a staff scientist at Los Alamos National Laboratory (LANL) in the Materials Physics and Applications Division. Her research career has been defined by advancing the understanding of deformation and failure in materials under extreme conditions, with particular emphasis on high strain rate phenomena relevant to national security and advanced manufacturing. She has led experimental and modeling efforts to uncover how microstructure, defects, and interfaces control mechanical response across a wide range of alloys and composites.

Building on this foundation, Dr. Fensin has recently expanded her portfolio to include AI- and automation-driven materials discovery, serving as Principal Investigator on several projects that integrate machine learning with high-throughput experiments and autonomous laboratories. Her group’s work explores the strengths and limitations of AI in predicting alloy performance and demonstrates how thin film screening, bulk validation, and automated synthesis can be connected in closed-loop workflows for accelerated discovery.

She received her Ph.D. in Materials Science and Engineering from the University of California, Davis, and has published widely on high-entropy alloys, shock physics, and automated approaches to alloy design. At LANL, she collaborates across disciplines to pioneer new paradigms for both fundamental understanding and rapid innovation in structural materials.

Abstract

The search for next-generation materials increasingly demands approaches that are faster and more predictive than trial-and-error. Our work began by exploring thin film deposition as a high-throughput method to screen refractory high-entropy alloys. Combinatorial sputtering allowed us to create entire libraries of compositions and rapidly probe phase stability and hardness trends. Thin films proved powerful for capturing intrinsic effects, such as the stability of single-phase BCC alloys, but direct comparisons with arc-melted bulk samples exposed their limits. Microstructural evolution—grain coarsening, segregation, and defect formation—often broke the simple link between film hardness and bulk yield strength. These insights motivated us to expand from thin films toward systematic bulk synthesis and validation.

To accelerate this process, we have coupled artificial intelligence (AI) and machine learning (ML) with experimental design. Our models predict yield strength and ductility across multi-principal element alloys, narrowing vast compositional spaces to promising candidates. Yet they also reveal their blind spots: defect-driven phenomena like segregation-induced embrittlement remain difficult to capture.

I will also introduce our automated laboratory platforms, where alloy synthesis, property measurement, and characterization are integrated into closed-loop, “self-driving” workflows. These systems enable rapid iteration between AI predictions and experiment while building the rich datasets needed to improve future models.

Together, thin film screening, bulk validation, and AI-driven automation point toward a new paradigm in materials discovery—where human intuition, machine learning, and autonomous laboratories combine to design structural alloys with unprecedented speed and precision.

Failing Fabulously: Vogue Challenging Niche Large-Scale Bone Repair Research Missteps into Broad Impact Innovations

Sara McBride-Gagyi, PhDAssistant ProfessorDepartment of Biomedical EngineeringThe Ohio State University

Abstract:Research rarely unfolds exactly as planned. Despite careful preparation and well-designed protocols, unexpected outcomes — and outright failures — are an inevitable part of experimental science and engineering. Yet these challenges are seldom shared publicly, leaving many trainees and early-career researchers feeling isolated or discouraged when things go awry.

In this talk, Dr. Sara McBride-Gagyi will share two recent projects from her lab related to her larger research on bone regeneration that faced significant, unforeseen setbacks — challenges that could easily have been dismissed as fatal failures that wasted valuable time and resources. Instead, through creative problem-solving and critical re-evaluation, her team turned these obstacles into opportunities, ultimately generating results and innovations more impactful than the original aims.

Dr. McBride-Gagyi will walk through each project chronologically, highlighting the engineering design pivots, decision-making processes, and lessons learned along the way. She will conclude with a discussion of how these experiences are being reframed for publication and dissemination — underscoring the value of transparency, adaptability, and perseverance in the scientific process.

Polymer Chain-End Chemistry: Unlocking Next-Generation Functional Materials

End-group functionalization has become a powerful and versatile strategy in polymer science, enabling precise control over physical properties, nanoscale self-assembly, and interfacial functionality without modifying the polymer backbone. In our group’s research, we have investigated how tailored end groups affect intrinsic polymer characteristics such as thermal transitions, solubility, and crystallization behavior, and how end-group interactions direct polymer self-assembly, particularly by modulating chain packing, interfacial curvature, and phase behavior in block copolymer systems, including the formation of complex network morphologies. Our goal is to develop synthetic methodologies for polymers with rationally designed end-functional groups, allowing systematic study of their thermodynamic phase-transition behavior through precise control of molecular interactions. By identifying and tuning key variables, our work aims to deepen fundamental understanding of polymer science. These insights highlight the transformative potential of end-group chemistry for next-generation polymer materials and provide a foundation for designing functional nanomaterials for emerging applications, including solid-state battery electrolytes, mechanical metamaterials, and optical metamaterials.

Nanoscale and Polarization Engineering: Unlocking New Frontiers with III-Nitrides

Abstract: Wide and ultrawide bandgap semiconductors offer unprecedented opportunities to address some of the most critical challenges we face in the next decades: energy efficiency, clean energy, environmental sustainability, and quantum information. In this talk, I will present some recent advances of nanoscale and polarization engineering of (ultra)wide bandgap III-nitride semiconductors and their emerging applications in next-generation microelectronics and photonics. By exploiting the strong excitonic effect in extreme quantum-confined nanostructures, conventional low-efficiency AlGaN can be turned into high-brightness deep-ultraviolet emitters, which offer the only alternative technology to replace mercury lamps for water purification/disinfection. The strong excitonic effect can be further exploited to achieve ultrahigh efficiency nano-LEDs to power future virtual/augmented reality. I will also discuss the recent discovery of ferroelectricity in III-nitride semiconductors, which leads to dramatically enhanced linear and nonlinear optical properties, piezoelectric response, and reconfigurability, that are urgently needed for integrated quantum photonics for information processing, acousto-electronics for 5G/6G technologies, memory-in-computing in harsh environments, and light-driven artificial photosynthesis for clean energy.

Efficient Tritium Extractor Design Enabled by High-Fidelity Simulation Tritium is the essential fuel in D-T fusion reactions, which underpin both inertial confinement and magnetic confinement fusion concepts. Given the extremely limited natural supply, in-situ breeding is the only viable pathway to sustain commercial fusion power. Liquid blankets containing ⁶Li, such as molten salts FLiBe and FLiNaK, are particularly promising because they enable both tritium breeding and efficient thermal management. Molten fluoride salts are especially attractive as coolants due to their excellent thermal and neutronic properties, as well as their inherently low tritium solubility. While significant research has been devoted to breeding mechanisms, tritium extraction remains relatively understudied, which creates a critical bottleneck in the D-T fuel cycle.

In this talk, I will present two ongoing efforts to design efficient tritium extractor concepts, i.e., both permeator against vacuum (PAV) and gas-liquid contactor (GLC), using high-fidelity simulations. I will demonstrate that advanced extractor design requires resolving a coupled multidimensional, multiphase transport problem. High-fidelity modeling provides detailed insights into local transport phenomena that are otherwise difficult to probe experimentally. With the added transport physics incorporated into existing CFD tools, we are well-positioned to perform refined parametric studies and optimize extractor geometries to advance tritium management strategies for fusion systems.

Abstract

Since the first discovery of ferroelectricity by Joseph Valasek in 1920, the field of ferroelectrics has been largely focused on oxide-based materials and devices. Recently, it has been shown that, the incorporation of group IIIB elements, e.g., Sc and Y, can transform conventional III-nitride semiconductors to be ferroelectric, with significantly enhanced electrical, dielectric, piezoelectric, catalytic, and linear and nonlinear optical properties. As such, ferroelectric nitride semiconductors have garnered significant attention for a wide range of applications in high power, high frequency, and high temperature electronics, optoelectronics, ferroelectrics, acoustoelectric, photocatalysis, and quantum photonic devices and systems. In this presentation, I will discuss the underlying physics and mechanisms of significantly enhanced piezoelectric response, ferroelectric switching, domain wall kinetics, and polarization dynamics. Additionally, the obstacles currently faced by nitride ferroelectrics in practical applications will be presented, followed by in-depth discussions of potential solutions, future research directions, and the prospects for further developments in this emerging field.

Closing the Loop on Machine Learning: A Perturbation Analysis Approach to Decision-Dependent Distribution Shift

As data-driven methods are deployed in real-world settings, the processes that generate the observed data will often react to the decisions of the learner. For example, a data source may have some incentive for the algorithm to provide a particular label (e.g. approve a bank loan), and manipulate their features accordingly. In this talk, I will present our recent work on analyzing this decision-dependent distribution shift through the lens of perturbation analysis in control theory. This framework allows us to consider settings with multiple equilibria and characterize the regions of attraction for each equilibrium, which is observed in practice: learning algorithms can settle into echo chambers, and characterizes the set of initial conditions which leads to each ultimate outcome. Additionally, I will discuss how these methods can be computationally calculated using integral quadratic constraints, how they can be made distributionally robust, and how it can be used for trajectory predictions for robotic crowd navigation.
