Abstract

We analyzed Zn-doped SnTe-based thermoelectric materials via transmission electron microscopy (TEM). The high-resolution TEM micrographs showed a doublet periodicity of the {1 1 1} lattice planes and the corresponding fast Fourier transform patterns revealed two sets of superstructure reflections having symmetrical intensity. The TEM results indicated the existence of a partially ordered CuPt-type structure in the Sn_1–xZn_xTe matrix; twinning bands were also observed in some regions.
