Abstract

The specific features in the behavior of deformation characteristics of low-ohmic p-type germanium single crystals subjected to different types of combined plastic deformation and the anisotropy of the electrical resistance of specimens in the longitudinal and transverse directions have been investigated. Both the acceptor and donor actions of dislocations have been observed in the motion of charge carriers along the direction of compression of the specimen. Under conditions of the joint action of a weak magnetic field and a combined plastic deformation, a decrease in the macroplasticity effects has been revealed. Anisotropy of the electrical resistance of p-Ge specimens in the longitudinal and transverse directions has been found. A possible explanation of the observed effect is given.
