•Microcrystals of Sb2Te3 are grown by the physical vapor transport (PVT) method.•Structure of Sb2Te3 is determined by single crystal structure analysis.•Spectroscopic parameters of Sb2Te3 microplates are measured with Raman spectroscopy.
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 ~200 μm. 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) Ǻ, 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.
