## Abstract The complex band structures, the imaginary parts of the dielectric constant, and the densities of states of electrons in amorphous Ge and Si are calculated using a generalized pseudopotential formalism based on the Green's function techniques. The short range order is assumed to be the
Using an empirical model for the density of states functions associated with hydrogenated amorphous silicon, with defect states taken into account, we examine how the distributions of such states shape the optical response of this material. The contributions to this response attributable to the vari
