Abstract:
1. A diode, comprising: a first III-N material layer; a second III-N material layer on the first III-N material layer, the second III-N material layer being compositionally different from the first III-N material layer, wherein the first and second III-N materials are part of a III-N stack, and a 2 DEG channel is in the second III-N material layer adjacent to the first III-N material layer because of a compositional difference between the first III-N material layer and the second III-N material layer; and a first terminal and a second terminal; wherein the first and second III-N material layers are N-polar or nitrogen-terminated semi-polar material; the first terminal is an anode comprising a Schottky contact with an N-face of the III-N stack; and the second terminal is a single cathode in ohmic contact with the 2 DEG channel.
