CURRENT DRIVEN PLASMA INSTABILITIES IN LOWER DIMENSIONAL SYSTEMS

摘要

Our earlier work on the possibility of spontaneous generation of plasma waves in current driven lower dimensional solid state systems is reviewed and extended, and new directions are suggested. Feasibility of plasma wave generation has been shown for uniform lower dimensional systems, and some modulated systems. The merits and problems for each system are enumerated. New directions to circumvent some of these problems are suggested. Prospects for experimental verification and potential device applications are discussed.
