Abstract
Films of were prepared via atomic layer-by-layer epitaxy both as standard solid-solution alloys and as -site-ordered superlattices of and layers. The transport properties were similar, although with a shifted and broadened metal-insulator transition temperature in the ordered material. Transport noise near was also similar, in both cases revealing a narrow peak in noise magnitude versus temperature. The phase coexistence region near has little dependence on the intrinsic disorder of the chemical alloy.
