HIGH POWER GALLIUM NITRIDE ELECTRONICS USING MISCUT SUBSTRATES

摘要

An electronic device includes a III-V substrate having a hexagonal crystal structure and a normal to a growth surface characterized by a misorientation from the <0001> direction of between 0.15° and 0.65°. The electronic device also includes a first epitaxial layer coupled to the III-V substrate and a second epitaxial layer coupled to the first epitaxial layer. The electronic device further includes a first contact in electrical contact with the substrate and a second contact in electrical contact with the second epitaxial layer.
