Ultra-Wide-Bandgap Semiconductors: Materials Opportunities and Challenges

Ultra-wide-bandgap (UWBG) materials have the potential to access levels of performance that are extraordinarily superior to those of the currently available narrower-bandgap materials. Areas of impact include high-power and RF electronics as well as passive components, deep-UV optoelectronics, and extreme-environment applications. Several UWBG materials, in particular, high-Al-content AlGaN, Ga2O3, and diamond, have advanced to the point where their tantalizing advantages are realizable. This presentation will provide an overview of the status of these materials and the opportunities and challenges for further advancement. This will include other, less-mature UWBG candidates and the challenge of controlled doping, which cross-cuts all UWBG materials. (Extended abstract uploaded as pdf) Comments: This is for an invited talk in a special session of GOMACTech-17 Conference entitled "Session 35: Ultra Wide Band Gap Semiconductors." I will be one of four speakers highlighting the findings from a comprehensive review on the status of UWBG semiconductors, materials, and applications."
