摘要
A special matrix formulation for the optical absorption coefficient of amorphous tetrahedrally bonded semiconductors is presented. This formulation involves the dipole-moment matrix element and a matrix element corresponding to the total electronic density of states with respect to optical transitions between conduction-band states and valence-band ones.
