Abstract
The order-dependent valence-band splitting and direct-gap reduction in spontaneously ordered indirect-gap AlInP2 are determined by dark-fiel d spectroscopy at room temperature. Similar to direct-gap GaInP2 both parameters depend on the degree of long-range CuPtB-type order. We obt ain the direct gap for disordered and the order induced changes of the spin-orbit splitting and the crystal-field splitting normalized to th e direct-gap change for perfectly ordered AlInP2.
