Abstract
Spontaneous CuPt-like ordering of GaxIn1−xP causes a splitting at the valence band maximum (VBM) and induces an anisotropy in the intensities of the transitions between these split VBM components and the conduction band minimum. We calculate these intensities as function of ordering parameter η, and show that the transition intensities depend strongly on the light polarization ê and the degree of long-range order η in the sample. Furthermore, for sufficiently ordered single-subvariant sample, 100% spin polarization of emitted photoelectrons is predicted.Keywords
