Consistency of crystal-lattice parameters and thermalexpansion coefficients in five-component heterostructures based on compounds AIIIBV

The possibility of expansion of the limits of variation in the width of the forbidden band in five component solid solutions of compounds A^IIIB^V with consistency of crystallattice parameters and thermal-expansion parameters of the binary substrate and epitaxial layer is analyzed. Possible regions, and the corresponding character, of variation in composition in five-component solid solutions of compounds A_IIIB^V with simultaneous consistency of the crystal-lattice parameters and thermal-expansion coefficients with the binary substrates are identified.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 1, pp. 59–64, January, 1989.
