Abstract

The triple-period (TP)-A and CuPt-A type ordering, which have been so far reported only for MBE grown alloys, were observed, in addition to CuPt-B type ordering, in Al0.5In0.5As alloys grown by MOVPE at 500°C. This indicates that (2×3) and (1×2) surface reconstructions occur on the surface even during MOVPE growth, although the (2×1) surface reconstruction and CuPt-B type ordering are dominant for the growth conditions examined.

[3 Note added: TP-A type ordering was recently observed as a dominant superstructure in small-amount-of-Sb doped GamnP grown at a high temperature of 650°C, in which temperature CuPt-B type ordering is observed without Sb doping. This has been ascribed to the very low volatility of Sb, compared to Ichihashi, P. T., Kurihara, K., Nishi, K., and Suzuki, T.; Submitted to Jpn. J. Appl. Phys.Google Scholar
