The features of variband single-crystal structures based on Si1-xGex (0 < x < 1), which have been grown on Si(111) substrates from a tin solution-melt by liquid-phase epitaxy have been experimentally investigated and analyzed. A mechanism for the growth of such structures is proposed, and the reason for the greater thickness of the deposited lms on the upper substrates for liquid-phase epitaxy is explained based on the RayleighTaylor instability phenomenon. Optimal technological regimes for obtaining epitaxial layers and structures are predicted.
