摘要：

Self-consistent electronic structure calculations together with a structural model are used to study the effect of short-range atomic order on the optical properties of otherwise random Al0.5Ga0.5As, Ga0.5In0.5P, and Al0.5In0.5As alloys. We find that clustering can reduce the direct band gap of these alloys by as much as 100 meV Furthermore, sufficiently strong clustering is predicted to transform Al0.5Ga0.5As into a direct gap material.
