Abstract

At room temperature, crystals of α-GeTe are invariably fragmented into domains separated by interfaces of two different types: twins and inversion boundaries. The inversion domains can be identified by making use of specific contrast effects occurring in non-centro symmetrical crystals. The geometry of the twins is determined by means of diffraction patterns. The fine scale fragmentation may be responsible for the extreme brittleness of the material and for the large figure of merit as a thermoelectric.
