Local Atomic Arrangement in an In0.53Ga0.47As Quasi-Binary Alloy Grown by Liquid-Phase Epitaxy

Abstract
Weak diffuse scattering was observed in the small-angle scattering region from the In0.53Ga0.47As alloy, which is theoretically found to originate from an atomic configuration on the group III sublattice. The experimental results could be explained in terms of the existence of a short-range ordered configuration. Such a deviation from the randomness was limited in terms of the volume of a unit cell, but no long-range order correlation was observed.
