After considering both the surface phonons and configurational entropy, (a) the fraction of the dominant InAs (001) reconstructions. Fraction of the dominant InAs (001) reconstructions at a fixed P of 4 × 10−9 atm (b) without including the c(4 × 4) heterodimers, and (c) including all the c(4 × 4) heterodimers.
