Abstract

The problems of defining an electronic density of states for amorphous semiconductors are summarized. A new equilibrium statistical-mechanical model for the structure and electronic properties of disordered systems is discussed and applied to the case of hydrogenated amorphous silicon (a-Si:H). The difficulty in treating non-equilibrium effects is briefly analyzed, and some of the unresolved controversies with regard to the density of states in a-Si:H are enumerated.
