Microwave and Terahertz Applications of Two-Dimensional Electron Systems

Abstract

The microwave and terahertz- bands of the electromagnetic wave spectrum offer many desired characteristics in the areas of communications, chemical sensing, and subsurface imaging. Yet, associated applications have not been fully realized because the present semiconductor technology has been unable to fully provide for existing needs. This project aims to continue a research- and application-oriented- study of microwave/terahertz- photoexcitation-induced physical phenomena in the GaAs/AlGaAs, graphene, and hybrids of these two material systems, with the goal of advancing the capability in the frequency range between the upper microwave (f > 50 GHz)- and lower terahertz (f < 1 THz) - bands. This study could lead to new radiation sensors, modulators, emitters for the above mentioned upper-microwave- and lower terahertz- portions of the electromagnetic wave spectrum.
