Solid-state electronics powers today’s information technology. Researchers in this area design and fabricate next-generation electronic devices and develop techniques for processing information using such devices. Current research topics include wide-bandgap semiconductor devices for power and high-speed radio-frequency devices, a wide range of semiconductors and their heterostructures for optoelectronics, flexible and printed electronics, bioelectronics, two-dimensional semiconductor devices, as well as micro- and nano-electromechanical devices and systems. ECE researchers in this area are also engaged in new cross-disciplinary efforts on campus in the emerging field of quantum science and engineering. Research is supported by state-of-art facilities for clean-room fabrication and characterization, which are operated by the Wisconsin Centers for Nanoscale Technology.
Located in a lab within Engineering Hall, PhD student Qinchen is using a microscope to locate the devices on a test wafer. Needle probes are then used to supply electrical signals to light-emitting diodes to observe their optical behavior. These light-emitting diodes (LEDs) and LASERs use Gallium Nitride and its alloys to produce Ultraviolet, visible and Infrared light as shown at the top of this page. ECE researchers are focused on the design and growth of gallium nitride and related materials, which are wide- and ultra-wide-bandgap semiconductors.
