Clustering and Ordering in III-V Alloys.
Abstract
The III-V semiconducting alloys are typically grown by epitaxial techniques at temperatures where, in the absence of substrate effects, they are thermodynamically unstable. This can result in problems associated with clustering of like atoms or ordering of unlike atoms. Long-range ordering could yield interesting III-V ternary compounds. Several concepts are discussed which could reduce clustering and promote long-range ordering in III-V alloys. Recent results indicate that the local atomic structure in GaxIn1-xAs is chalcopyrite-like and that long-range ordering may be thermo-dynamically feasible. Kinetically, it is suggested that growth on substrates could promote long-range order.
