Abstract

Modulated molecular beam epitaxy (MMBE) has been demonstrated to be useful in controlling group-V alloys such as InAs_xSb_1-x and AlAs_xSb_1-x. Further studies of the MMBE grown InAs_xSb_1-x ordered alloys and InAs/InAs_xSb_1-x superlattices by using cross-sectional scanning tunneling microscopy show well defined interfaces between InAs_xSb_1-x ordered alloys and InAs. Clear composition modulation is observed in the InAs_xSb_1-x ordered alloy layers. Transmission electron diffraction and microscopy, X-ray diffraction, and low temperature photoluminescence experiments show no obvious sign of CuPt orderings. These results suggest that MMBE provides a possible means to bypass the ordering problem of InAs_xSb_1-x random alloys.
