Реферат:	eng: High-quality Bi 2Te 3 microcrystals have been grown by 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 ∼100 μm. The phase composition of grown crystals has been identified by X-ray single crystal structure analysis in space group R3m, a=4.3896(2) Å, b=30.5019(10) Å, Z=3 (R=0.0271). Raman microspectrometry has been used to describe the vibration parameters of Bi 2Te 3 microcrystals. The FWHM parameters obtained for representative Raman lines at 61 cm -1 and 101 cm -1 are as low as 3.5 cm -1 and 4.5 cm -1, respectively. © 2012 Elsevier Ltd. All rights reserved.
