Abstract

Rhombohedral-cubic transformation in Bi2 Te3 doped- Pb1-x Gex Te alloys is presented. Samples of Bi2 Te3 doped Pb1-x Gex Te were prepared by powder metallurgy approach. These powder samples were examined by high-temperature X-ray diffraction (XRD) and scanning electron microscopy/energy dispersive spectroscopy. A bulk (pressed powder) cylindrical specimen was used for dilatometery characterizations. According to the XRD examinations it seems that upon increasing the temperatures a continuous transformation occurs from the rhombohedral to the cubic phase, accompanied by the formation of a small amount of the phase Ge0.74 Pb3.26 Te4.
