Description

The method of investigation of the chemical composition for quaternary heterostructures has been developed. To this end X-ray high resolution diffractometry and RBS methods were applied. This method consists in finding a best fit between experimental diffraction pattern and theoretical one calculated, employing Darwin dynamical diffraction theory for a given model of heterostructure. This procedure was applied to determine the chemical profile in the growth direction for InGaAsP/InP superlattices that were grown by MOCVD technology on 001 InP substrate. The relations between the chemical composition of InxGa1-xAsyP1-y layer, its lattice parameter, optoelectronic properties and growth conditions were found. (author)
