In this program we have developed a Novel Approach for New Radiation Sources based on current driven plasma instabilities CDPI in layered solid state systems. We have demonstrated the feasibility of generating CDPI in a variety of systems, and of conversion of the energy of the growing plasma waves to electromagnetic radiation. We have identified the most promising candidates for experimental verification and device applications within the class of uniform lower dimensional systems. In addition, we have preliminary indications that modulated lower dimensional systems would significantly enhance these effects. We have also stimulated experimental efforts to confirm the results of our investigations.
