Abstract

Temperature dependent phase transitions of compounds (GeTe)(n)Sb₂Te₃ (n = 6, 12, 15) have been investigated by in situ microfocus Laue diffraction. Diffusion processes involving cation defect ordering at similar to 300 degrees C lead to different nanostructures which are correlated to changes of the thermoelectric characteristics.
