Our group explores wide bandgap (WBG) and ultra-wide bandgap (UWBG) materials and devices in electronic and photonic applications. Our research interests span the physics, design, simulation, fabrication, characterization, reliability, robustess, packaging, and circuit applications of WBG and UWBG devices. Our research emphasizes on the fundamental understanding of UWB/UWBG devices, their new applications in power, RF, sensing, and computing applications, as well as the relevant material-device co-design with machine learning. Our group highlights a full-stack research scope from materials and devices to circuits and algorithms, and the seamless collaborations with the industry.

OPENINGs: We have Ph. D. openings in the Fall 2022. The ideal candidates are expected to have a background in semiconductor devices or power electronics. Device physics background and cleanroom fabrication experience are strong plus. We also have immediate postdoc opening with a desired background in gallium nitride device process and IC designs. In addition, we host remote online research projects on device and converter modeling. The ideal candidates are undergraudate or graduate researchers with a solid background in device physics and device/circuit modeling. 

For anyone interested in the above opportunities, feel free to contact Prof. Yuhao Zhang with a CV and representative publications.
