抄録: The high-performance thermoelectric compound Ti0.5(Zr0.5Hf0.5)0.5NiSn0.998Sb0.002 with half-Heusler lattice was studied by X-ray diffraction (XRD) and transmission electron microscopy (TEM). Each half-Heusler peak in the XRD pattern was accompanied by a bump at the high-angle side. Granular domains, a few nanometers in size, were observed in a bright-field TEM image. Fourier transformation and inverse Fourier transformation of the high-resolution TEM image revealed that the granular structure consists of half-Heusler domains with ordering and with disordering between second nearest neighbor atoms.
