Terahertz and Microwave Devices Based on the Photo-Excited Low Dimensional Electronic System
Abstract
This experimental project funded by the ARO under grant # W911NF-10-1-0450 was concerned with the study of the electrical properties of low dimensional systems in a steady state non-equilibrium condition that is realized by photo-exciting the system with electromagnetic waves in the microwave and THz parts of the radiation spectrum, in the presence of a weak magnetic field. In this regime, it has been found, for example, that dissipative electrical resistance of a semiconductor can vanish over broad magnetic field intervals, as novel magnetoresistance oscillations are induced by photo exciting a high mobility low dimensional electron system. This research aimed to advance the understanding of such radiation-induced phenomena in the two-dimensional electron system, while helping to develop new concepts for terahertz devices.
