Patent ID: 8907378

Claim:
A device, comprising: a source for transmitting an electronic charge; a drain for receiving the electronic charge; a first stack for providing at least part of a conduction path between the source and the drain, wherein the first stack includes a first set of layers of a first polarity, the first set includes a first gallium nitride (GaN) layer of the first polarity; a second stack for providing at least part of the conduction path between the source and the drain, wherein the second stack includes a second set of layers of a second polarity, the second set includes a second gallium nitride (GaN) layer of the second polarity, and wherein the first polarity is different from the second polarity; an interlayer deposited between the first and the second stacks; and at least one gate operatively connected to at least the first stack for controlling a conduction of the electronic charge, such that, during an operation of the device, the conduction path includes a first two-dimensional electron gas (2DEG) channel formed in the first GaN layer and a second 2DEG channel formed in the second GaN layer.
