The design of a sublimation system in a closed space for carrying out technological processes of АIIВVI materials deposition, which can be used to obtain photoelectric structures with graded gap active layers based on solid solutions of these materials, is proposed and implemented. The physico-chemical bases of the technology have been established and the optimal technological regimes for obtaining CdSeхTe1-х graded gap semiconductor films are worked out. An experimental and theoretical study of structural, optical, band-energy characteristics has been carried out. The values of effective masses, optical parameters, acoustic velocity, Debye temperature and elastic properties (bulk modulus, shear modulus, Young's modulus and Poisson's ratio) of CdSeTe solid solutions have been established   Product Description popup.authors Vysochans`ka (Zmiiovska) Emilia O Honchar Fedir M Danylov Andrii B Kashuba Andrii I Krukovskiy Semen I Lopatynskyi Ivan Ye Petrus Roman Yu Semkiv Ihor V Solovyov Mykola V Ukrainets Natalia A popup.nrat_date 2021-01-05 Close
