摘要
It is shown how, and why, Cayley trees (Bethe-lattices) are useful models for studying elementary excitations in disordered solids. Special attention is focused on the effects of disorder on the electronic states of various amorphous bonded solids. Specific examples are drawn from problems involving: (1) bond-angle distortions and localized states in amorphous Ge, (2) hydrogen configurations in hydrogenated amorphous Si, (3) bonding-coordination defects in amorphous As and (4) amorphous SiSiO2 interfaces. © 1979.
