Документ Barrier structures on the basis of graded-band-gap CdHgTe obtained by evaporation-condensation-diffusion method(2016) Świątek, Z.; Vlasov, Andriy; Ivashko, M.; Petryna, R.; Bonchyk, A.; Sokolovskii, B.; Власов, Андрій; Петрина, РоманThe paper presents the methods of obtaining photovoltaic structures based on CdXHg1- XTe graded-band-gap epitaxial layers. Barriers in these structures were formed by solid phase doping of the material with low-diffusing impurities (As). High-temperature diffusion of acceptor impurity (As) in intrinsically defective material of n-type conductivity as well as ion introducing the donor impurity (B) in uniformly doped during the epitaxy process material of p-type of conductivity have been used. The possibility of creating multi-element graded-band-gap photovoltaic structures suitable for broad band detection of infrared radiation as a result of epitaxial growth by evaporation-condensation-diffusion method has been demonstrated.Документ Controlled arsenic diffusion in epitaxial CdXHg1-XTe layers in the evaporation-condensation-diffusion process(2002) Vlasov, Andriy; Pysarevsky, V.; Storchun, O.; Shorchenko, A.; Bonchyk, A.; Pokhmurska, H.; Barcz, A.; Swiatek, Z.; Власов, Андрій; Писаревський, В.; Сторчун, О.; Шорченко, А.; Бончик, А.; Похмурська, Г.; Святек, З.The results of controlled doping of CdxHg1yxTe epitaxial layers are presented. The investigated layers were obtained by the evaporation–condensation–diffusion method in the process of isothermal growth. The process of auto diffusion from the solid phase was investigated. This process consists in the diffusion of As dopants from CdTe substrate into the grown epitaxial layer. Two types of CdTe substrates, uniformly doped in the process of synthesis and unalloyed with ion implanted surface layer, have been used as sources of As diffusant. Comparative analysis of galvanomagnetic measurements and SIMS spectra was carried out. The results of investigations indicate the very high, almost 100%, electrical activity of As dopants in the CdxHg1yxTe epitaxial grown layer. 2002 Elsevier Science B.V. All rights reserved.
