The nature of the electronic states of a disordered system. II. Extended states

Abstract

For pt. I see ibid., vol. 5, 1183 (1972). The general selfconsistent method derived in pt. I is used in a description of the extended states of an electron in a disordered system. The properties of the localized and extended states near the transition energy are compared, and the continuity of the relation between E and k, (E approximately k⁵3/), is shown across the mobility edge.
