Ultra-wide power electronics is an emerging field based on advances in the growth of ultra-wide bandgap (> 4.5 eV) semiconductors. This opportunity involves the characterization of such materials and the fabrication and characterization of electronic devices (diodes, transistors, etc.) based on or integrating such materials. Fundamental understanding of material properties such as doping, defects, and conductivity is needed. Advanced characterization techniques are available and tailoring them for use with ultra-wide bandgap semiconductors is a part of this project.
