INHOMOGENEITIES IN Pb1-x-y Snx Mny Te CRYSTALSS. Miotkowska, J. Kachniarz, E. Dynowska, T. Story, A. Jędrzejczak Institute of Physics, Polish Academy of Sciences, Al. Lotników 32/46, 02-668 Warsaw, Poland Single crystals Pb1-x-y SnxMny Te alloys were grown by the Bridgman method. The nominal values of x and y were 0.29 < x < 0.80 and 0.01 < y < 0.16. The investigations were carried out using SEM, ED EPMA and X-ray diffraction on powders. Analysis of the real chemical composition of the samples showed that any inappropriate ratio of concentrations of Pb and Sn leads to creation of MnTe2 precipitates. Close X |
