Abstract

Transmission electron microscope studies were made of CuPt-type ordering in molecular beam epitaxial InAsySb1-y natural strained layer superlattices and homogeneous layers grown at temperatures in the range 295-470°C. Ordering occurs with a maximum at a growth temperature of 370-400°C, individual (1̄11) and (11̄1) ordered domains up to 10 nm in size are present, and there is a modulation of periodicity 3 d 110 within the layers, where d110 is the (110) lattice spacing. The latter correlates with a [2×3] atomic surface reconstruction present during growth.
