摘要：

The spontaneously ordered Ga0.52In0.48P alloy comprises domains, each of which is characterized by an order parameter eta. We have used the low-temperature near-field photoluminescence technique with a high spatial resolution (less than or equal to 2500 Angstrom) to study the statistical distribution of the order parameter eta of single-variant ordered alloys. We have found that for large-domain samples, eta 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 eta.
