We present the results of a theoretical study on the structural stability of InAs under high pressure, with a focus on the pressure regime past the first transition from the low‐pressure zincblende phase to the rocksalt (NaCl‐type) phase. We have examined several candidates proposed for low‐enthalpy phases at higher pressures, among them the super‐Cmcm structure observed in InSb at moderately high pressure and the B10 structure, which is a distortion of the CsCl structure. Our results reproduce the established sequence of transitions and shed further light on the higher pressure regime of this material. (© 2007 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
