Claim Text:
1. An enhancement mode high electron mobility transistor device, comprising: a heterostructure region including a 2DEG therein, the heterostructure region comprising a channel layer comprising a first GaN material and a tertiary or quaternary layer comprising a second GaN material, the second GaN material having an aluminum composition between 0 and 1 or equal to 1; a p-type cap on the layers that form the heterostructure region, the p-type cap including an MN layer and a p-type AlGaN or AlInGaN layer; a dielectric layer contacting the layers that form the heterostructure region and adjacent to the cap; and a gate on the cap; wherein the device is an N-face enhancement mode high electron mobility transistor device.
