Abstract : In this program, we have identified theoretically the most promising candidates for current driven plasma instabilities (CDPI) in semiconductor based systems: the modulated quantum wires and lateral surface superlattices (LSSL). Feasibility of CDPI at much lower driving fields, as compared to the corresponding uniform systems, was established. Investigation of CDPI in a superconducting system was continued in close collaboration with an experimental group. We have also developed contacts with a number of experimental groups to stimulate parallel efforts for verification of CDPI in layered semiconductor systems. A Workshop was arranged with ARO sponsorship, held at Boston College in August 1994, which brought together Dr. Ciftan (ARO), our group, and the experimentalists to discuss future efforts and collaborations.
