Abstract

We present experimental evidence for the spontaneous breaking of cubic symmetry in the band structure of films of Ga0 52 1n0 48P grown by organomeltallic vapor phase epitaxy on (100) GaAs substrates. We show how this effect is related to the spontaneous ordering of the alloy, and its correlation with the anomalous lowering of the band-gap observed in these films.
