Abstract

The paper proposes a novel approach to fabricate high performance microwave devices with non-ohmic contacts. Low contact impedance is achieved through a strong capacitive coupling between the metal electron and the high-density two- dimensional electron gas. This approach allows for a new device design with non-annealed or low-temperature annealed contacts and gate alignment-free technology. The application of capacitively coupled contacts for high-power microwave devices is demonstrated.
