Abstract
A transistor includes a III-N layer structure including a III-N channel layer between a III-N barrier layer and a III-N depleting layer, where the III-N channel layer includes a 2DEG channel formed adjacent an interface between the III-N channel layer and the III-N barrier layer; a source and a drain, each of which being directly connected to the III-N channel layer; a gate between the source and the drain, the gate being over the III-N layer structure, where the III-N depleting layer includes a first portion that is disposed in a device access region between the gate and the drain; and where the source electrically contacts the first portion of the III-N depleting layer, and the drain is electrically isolated from the first portion of the III-N depleting layer.
