Abstract
A method of fabricating an electronic device includes providing 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 method also includes growing a first III-V epitaxial layer coupled to the III-V substrate and growing a second III-V epitaxial layer coupled to the first III-V epitaxial layer. The method further includes forming a first contact in electrical contact with the III-V substrate and forming a second contact in electrical contact with the second III-V epitaxial layer.
