Original Abstract Submitted

A heterostructure-based high electron mobility transistor includes a channel region in which a two-dimensional electron gas is formed which is protected by insulating material. A control terminal contacts the channel region within an aperture in the insulating material. The control terminal includes a first metal layer that forms a Schottky contact to the channel region within the aperture and a gate electrode which overlies the first metal layer and the channel region and extends above the channel region adjacent to the aperture.
