Towards Experimental Verification and Device Applications of Current DrivenPlasma Instabilities in Solid State Systems

摘要

In this program, we have identified theoretically the most promising candidatefor current driven plasma instabilities (CDPI) in semiconductor based systems: the modulated lower dimensional systems. We also investigated the effects of a grating coupler and a strong magnetic field on CDPI in uniform two-dimensional electron gases. Significant progress was made in pursuing the goal of experimental verification of this phenomenon in superconductor based systems.
