Abstract

The order-dependent valence-band splitting and direct-gap reduction in spontaneously ordered indirect-gap AlIn(Formula presented) are determined by dark-field spectroscopy at room temperature. Similar to direct-gap GaIn(Formula presented) both parameters depend on the degree of long-range (Formula presented)-type order. We obtain the direct gap for disordered and the order-induced changes of the spin-orbit splitting and the crystal-field splitting normalized to the direct-gap change for perfectly ordered AlIn(Formula presented).
