Dislocation scattering and de Haas-van Alphen amplitudes

Abstract

The scattering of electrons by the long-range elastic strain field of an edge dislocation in a metal is treated in the Born approximation by explicitly incorporating the concept of a limiting scattering angle. Simple expressions are obtained for the field-dependent cross section, reciprocal relaxation time and Dingle temperature. The results are in satisfactory agreement with currently available experimental data. The relation of the theory to other theoretical approaches is discussed.
