Summary
Description
<p>Integration of graphene as the top metal on GaN Schottky. This will replace platinum, which is 50% transparent at the desired wavelength, with graphene, which has higher mobility and much higher transparency (&gt;90%). Develop a fabrication process for GaN Schottky and a chemical vapor deposition process for large area graphene. Develop a process to cleanly integrate single or multilayer graphene on GaN devices and pattern them. Develop a characterization scheme to determine the Schottky barrier height of graphene and device QE.</p>
