Isothermal annealing influence on structural defects and some characteristics of Bismuth Telluride wire crystals

Abstract

Possibilities to control microdefect formation in bismuth telluride wire crystals by choice of optimal modes of isothermal annealing are discussed. It is found that a decrease of density of structural defects, such as microcracks, dislocations, and twins after isothermal annealing leads to improvement of both mechanical and electric parameters.
