Реферат: | eng: High-quality Sb2Te3 microcrystals have been grown by the physical vapor transport (PVT) method without using a foreign transport agent. The microcrystals grown under optimal temperature gradient are well facetted and they have dimensions up to similar to 200 mu m. The phase composition of the grown crystals has been identified by the X-ray single crystal structure analysis in space group R-3m, a=4.2706(1), b=30.4758(8) angstrom, Z=3 (R=0.0286). Raman microspectrometry has been used to describe the vibration parameters of Sb2Te3 microcrystals. The FWHM parameters obtained for representative Raman lines at 69 and 111 cm(-1) are as low as 5 and 8.6 cm(-1), respectively. (C) 2013 Elsevier Ltd. All rights reserved.
