Electronic Density of States of Noncrystalline Si and Ge: I. Spherically Symmetric Interference Function Approach

Abstract

Abstract The electronic density of states have been calculated for amorphous and liquid phases of Si and Ge, using pseudopotential perturbation theory. These calculations are carried out on the basis of experimental radial distribution functions for the appropriate phases, and second order in electron energy. The density of states generated by this method compare favorably with those obtained by other computational methods.
