The status of atomic ordering in ternary and quaternary III–V compound semiconductors is reviewed briefly. Evidence favors the occurrence of CuPt-type ordering in these materials. Reconstruction at (001) surfaces is essential for the formation of the ordered structure that is metastable in the bulk. Ordering reduces bandgaps, and degradation resistance of light emitting devices is enhanced.
