Dysprosium-doping influence on the microstructure and texturing of bismuth-telluride thermoelectric materials

Abstract

The preparation and identification of microstructure features as well as the texturing of the thermoelectric material Bi₂-ₓSmₓTe₂.₇Se₀.₃ doped with dysprosium are considered. The textured compounds Bi₂-ₓDyₓ Te₂.₇Se₀.₃ with x = 0.0000; 0.0010; 0.0025; 0.0050; 0.0100, and 0.0200 were obtained by means of solvothermal synthesis of the original powders and their subsequent spark plasma sintering
