(a) Calculated surface energy of the InAs (001) reconstructions with low surface energy as a function of P and T. (b) (P-T) surface reconstruction diagram of the InAs (001) surface. (c) Calculated surface energy of the InAs (001) reconstructions with low surface energy as a function of T at fixed Ptotal of 4 × 10−9 atm. All figures were obtained without considering the surface phonons.
