Changes in the parameters of p-Ge compression curves for various methods of plastic deformation

Abstract

The behavioral features of deformation characteristics are investigated in p-type germanium single crystals under the combined action of electric current and temperature and separate exposure to electric current. The p-Ge resistivity decreases with increasing strain. When temperature and electric current jointly act on the single crystal, it is revealed that the resistance to deformation increases. In the case where only the electric current affects the compressed single crystal, there is enhancement in the plastic properties. Different deformation methods qualitatively affect the shape and parameters of curves. The surface microstructures of prepared deformed samples are studied. Possible physical explanations for the observed phenomena are proposed.
