Abstract:
1. A diode, comprising: a first III-N material layer; a second III-N material layer on the first III-N material layer, wherein the second III-N material layer has a thickness and a 2DEG channel is in 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; a first insulator layer on the second III-N material layer so that the second III-N material layer is between the first insulator layer and the first III-N material layer; and two terminals, wherein a first terminal is an anode that extends through an entirety of the thickness of the second III-N material layer to contact the first III-N material layer and form a Schottky contact with the first III-N material layer and has an extending portion that extends over the first insulator layer, and a second terminal is a single cathode in ohmic contact with the 2DEG channel.
