摘要：

We present an ab initio pseudopotential study of the cinnabar phases of GaAs and GaP, which are covalently bonded fourfold-coordinated structures formed from twisted tetrahedra. We find that these phases are not thermodynamically stable. We suggest, however, that cinnabar-GaP could be formed as a metastable phase by releasing pressure from the Cmcm phase, as recently observed in GaAs.
