Electropulsing-induced microstructure evolution of thermoelectric (Bi 0.25 Sb 0.75 ) 2 Te 3 thin films was studied by X-ray diffraction, scanning electron microscopy and Hall effect measurement techniques. Electropulsing-induced circular phase transformations and crystal orientation changes were detected and related to the changes in electrical conductivity of the thin...
