Evaluation of Bonding Orbitals in Amorphous Silicon by Means ofthe Chemical Pseudopotential Method

M. A. Grado Caffaro, M. Grado Caffaro

Abstract

The chemical pseudopotential method has been used by a number of workers in order to study the valence bands of amorphous tetrahedrally bonded semiconductors. However, various problems related to this method are unsolved. In this paper, a theoretical formulation tending to clarify some of these. problems is presented. This formulation concerns bonding orbitals and is valid, in principle, for amorphous silicon.
