Abstract
This paper deals with several problems related to the theory of amorphous semiconductors, some of which have remained unsolved despite the magnitude of the effort devoted to basic and applied research on these materials. I review recent progress, attempt to identify the essential remaining difficulties, and summarize new results of my own and those of my collaborators, as the case may be. The topics covered are band tails, the Lloyd model, shallow impurity levels, deep levels, excitons, electronic transport, and optical absorption. Several of these problems have been covered in recent publications [1–3], from which most of this work has been extracted.
