Abstract

We have succeeded in growing epitaxial layers and multilayer heterostructures of In1−xGaxAs1−ySby quaternary and InAs0.92Sb0.08 ternary alloys lattice matched to GaSb by molecular beam epitaxy. High quality epilayers with lattice mismatch Δa/a∼8×10−4, excellent morphology, and efficient photoluminescence were grown. The surface reconstructions during growth of these quaternary and ternary alloys were also investigated using in situ reflection high-energy electron diffraction.
