Abstract

The spontaneous long-range-order-induced splitting of the valence band of ${Ga}_{0.5}$ ${In}_{0.5}$ P is studied by polarized near-gap-excited photoluminescence and photoluminescence excitation. The results allow a direct determination of the size of the valence-band splitting and the relative ordering of the resultant states. Values obtained for the splitting are compared with recent calculations.
