Abstract

The spontaneously ordered (Formula presented) alloy comprises domains, each of which is characterized by an order parameter η. We have used the low-temperature near-field photoluminescence technique with a high spatial resolution (Formula presented) to study the statistical distribution of the order parameter η of single-variant ordered alloys. We have found that for large-domain samples, η varies only slightly between domains and the line width broadening of the excitonic photoluminescence peak comes mainly from alloy scattering within a single domain rather than from a broad distribution of η.
