Abstract:
A III-N device includes a III-N layer structure including a III-N channel layer, a III-N barrier layer over the III-N channel layer, and a graded III-N layer over the III-N barrier layer having a first side adjacent to the III-N barrier layer and a second side opposite the first side; a first power electrode and a second power electrode; and a gate between the first and second power electrodes, the gate being over the III-N layer structure. A composition of the graded III-N layer is graded so the bandgap of the graded III-N layer adjacent to the first side is greater than the bandgap of the graded III-N layer adjacent to the second side. A region of the graded III-N layer is (i) between the gate and the second power electrode, and (ii) electrically connected to the first power electrode and electrically isolated from the second power electrode.

Claim (Index 7):
The III-N device of  claim 6 , the III-N device having a threshold voltage, wherein a grading profile in the graded III-N layer is selected such that mobile charge in the 2DEG channel in an access region between the gate and the drain electrode is depleted while the gate is biased relative to the source electrode at a voltage lower than the threshold voltage and the drain is biased above a minimum voltage relative to the source electrode, but not depleted while the gate is biased relative to the source electrode at a voltage higher than the threshold voltage.
