A Theory of Glassy Semiconductors.
Abstract
A model for glassy semiconductors is discussed which provides for a generic description of a wide range of materials. The theory is based on the premise that the under lying disorder of the amorphous state requires a qualitatively different description. The major consequence of the lack of long-range structural symmetry is the enhancement of the electron-phonon interaction and the localization of eigenstates. Strong enough interaction leads to an effective attraction between localized electrons which accounts for both diamagnetism and optical transparency. The excitations on the ground state are derived and consideration of their relaxation leads to the existence of long lived states in a narrow region of the spectrum near the Fermi level. (Author)
