Present and future applications of amorphous silicon and its alloys

Abstract Thin films of amorphous silicon (a-Si:H) and its alloys prepared by the glow discharge decomposition of silane and appropriate gases, are presently incorporated into six commercial products and approximately twenty other applications have been proposed for these materials. This presentation will review the present applications and a number of those proposed for the future. Finally, some of the material and technological issues of current importance will be discussed.
