Malanych G. P. The influence of ethylene glycol on the chemical interaction of PbTe and Pb1–xSnxTe crystals with H2O2–HBr–ethylene glycol etching compositions [Електронний ресурс] / G. P. Malanych, V. M. Tomashyk, O. S. Lytvyn // Semiconductor physics, quantum electronics & optoelectronics. - 2017. - Vol. 20, № 1. - С. 91-95. - Режим доступу: http://nbuv.gov.ua/UJRN/MSMW_2017_20_1_15 The process of cutting, mechanical and chemical treatment of the PbTe and Pb1-xSnxTe crystal surface has been studied. The dependences of the chemical-mechanical polishing rate versus dilution of the base polishing etchant H2O2 - HBr - ethylene glycol by the ethylene glycol have been determined. The surface states after chemical etching have been investigated using electron, metallographic and atomic force microscopy as well as X-ray microanalysis. It has been shown that the surface state is improved after chemical etching. Efficient methods for washing the samples after different types of PbTe and Pb1-xSnxTe surface treatment (cutting the crystal, mechanical surface treatment, chemical removing the surface damaged layer) have been developed.
