This paper discusses the structural perfection, the lattice constant, and the electrophysical properties of sulfur doped epitaxial gallium arsenide layers, then studies them by means of a complex methods, varying the concentration of sulfur in the gaseous phase. The experimental data indicate that the sulfur atoms can exist in the GaAs lattice simultaneously in the number of states, namely in the form of substitutional and interstitial solid solutions, as well as in the form of presegregations or second phase segregations. At the maximum sulfur doping level second phase segregations are formed in the layers, which leads to an anamolous decrease in the lattice constant and the electron mobility.
