CXXIV. Statistics of the occupation of dislocation acceptor centres

Abstract

This paper is a sequel to a previous one (Read 1954) dealing with the acceptor centres associated with dislocations in germanium. The previous paper developed two approximations for the statistics of occupation of dislocation acceptors. This paper presents some further approximations that take account of the non-uniform spacing of accepted electrons along the dislocation. It also treats the case where the dislocation acceptors have a range of energy levels (rather than a single level). The several approximations are compared by plotting the fraction of acceptors that are full vs. temperature for a particular example.
