Compositional dependence of AlAsySb1−y ternaries on the ratio of Sb/As fluxes and on the substrate temperature

We present a systematic study of the compositional dependence of AlAsySb1−y layers, grown by molecular beam epitaxy, on the ratio of As to Sb fluxes and on the substrate temperature. The initial results clearly demonstrate that variations in the composition can be observed by changing the above-mentioned parameters. The emphasis of this communication is on understanding the qualitative trends of these dependencies.
