Abstract:

The nature of crystal orientation in SnSb2Te4 and PbBi4Te7 compounds was investigated. It was established that in the case of sublimation of SnSb2Te4 alloy on a celluloid film and rock salt without subsequent annealing thin ploycrystalline films are obtained. To obtain textured or monocrystalline film, it is necessary to sublimate this alloy on hot NaCl layers with subsequent annealing. When investigating samples of SnSb2Te4, the sublimation condition plays a greater role for the alloy. It was established that in the dependence upon the number of sublimation, the nature of orientation of crystals and chemical composition of the film change. The film of the basic alloy SnSb2Te4 is obtained at one sublimation only. It was established that the orientation of crystals of compounds PbBi4Te7 in thin layers at various annealing conditions is different. In contrast to SnSb2Te4 compound, the compound PbBi4Te7 does not change in composition from the sublimation conditions. Author
