Tomashyk V. M. Optimization of conditions for treatment of ZnSe crystal surfaces by chemical etching [Електронний ресурс] / V. M. Tomashyk, A. S. Kravtsova, Z. F. Tomashyk, I. B. Stratiychuk, S. M. Galkin // Semiconductor physics, quantum electronics & optoelectronics. - 2013. - Vol. 16, № 2. - С. 140-145. - Режим доступу: http://nbuv.gov.ua/UJRN/MSMW_2013_16_2_10 The process of chemical polishing the undoped and doped ZnSe crystals surface with H2O2 - HBr etchants has been studied. The dependence of the samples polishing rate on the concentration of H2O2 in HBr solution has been investigated. Surface states after chemical etching have been established using electron and atomic force microscopies, and it was shown that the surface state is improved after chemical etching. Etchant selection to develop slow polishing compositions for chemical-mechanical polishing the investigated materials has been made. Concentration regions of polishing solutions have been found for various types of ZnSe surface treatment: to remove the damaged layer, to control the etching rate, to obtain samples of a given thickness.

Stanetska A. S. Development, optimization and improvement of ZnSe crystal surfaces mechanical and chemical treatment and washing methods [Електронний ресурс] / A. S. Stanetska, V. N. Tomashyk, I. B. Stratiychuk, Z. F. Tomashyk, M. Yu. Kravetskyy, S. N. Galkin // Semiconductor physics, quantum electronics & optoelectronics. - 2015. - Vol. 18, № 4. - С. 416-421. - Режим доступу: http://nbuv.gov.ua/UJRN/MSMW_2015_18_4_9 The process of cutting, mechanical and chemical treatment of the undoped and doped ZnSe crystal surface has been studied. The chemical interaction of zinc selenide surface with bromine emerging solutions of H2O2 - HBr and H2O2 - HBr - organic solvent has been studied. The surface states after chemical etching have been investigated using electron, metallographic and atomic force microscopy, and it was shown that the surface state is improved after chemical etching. Etchant selection to develop slow polishing compositions for chemical-mechanical polishing of investigated materials has been made. Efficient methods for washing samples solutions have been developed after different types of ZnSe surface treatment: cutting of the crystal, mechanical surface treatment, chemical removing the surface damaged layer.

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.
