摘要：

Spontaneous (111) CuPt-like ordering has been widely observed in GaxIn1-xP lattice matched (x=x(0)) to a GaAs(001) substrate. This leads to a band-gap reduction Delta E(g) and to a valence-band splitting Delta E(12). We explore here the consequence of the coexistence of (001) epitaxial strain (produced by selecting x not equal x(0)) and (111) chemical ordering. This leads to distinct changes in Delta E(g) and Delta E(12) which could serve as new fingerprints of ordering.
