Spinodal decomposition of [Ga.sub.x][In.sub.1-x][As.sub.y][P.sub.1-y] quaternary alloys

Using X-ray structural analysis, scanning electron microscopy, atomic force microscopy, and photoluminescent spectroscopy, it is shown that it is possible to obtain a small-scale domain structure on the surface of liquid-phase epitaxial heterostructures. The domain structure emerges as a result of s...

Description
Summary:Using X-ray structural analysis, scanning electron microscopy, atomic force microscopy, and photoluminescent spectroscopy, it is shown that it is possible to obtain a small-scale domain structure on the surface of liquid-phase epitaxial heterostructures. The domain structure emerges as a result of spinodal decomposition of the [Ga.sub.x][In.sub.1-x][As.sub.y][P.sub.1-y] quaternary alloy due to immiscibility of its components and relaxation of its lattice parameter to surrounding layers.
