<p>A semiconductor device is described. In one embodiment, the device includes a Group-III nitride channel layer and a Group-III nitride barrier layer on the Group-III nitride channel layer, wherein the Group-III nitride barrier layer includes a first portion and a second portion, the first portion having a thickness less than the second portion. A p-doped Group-III nitride gate layer section is arranged at least on the first portion of the Group-III nitride barrier layer and a gate contact formed on the p-doped Group-III nitride gate layer.</p> |
