Show affiliationsWe study the behaviour of GaAs under a uniaxial compression using an ab initio constant-pressure technique and find that GaAs undergoes a first-order phase transition to a side-disordered orthorhombic Imm 2 structure via an intermediate state having the space group of
. The transition pathway and mechanism under uniaxial stress are found to be considerably different from those under the hydrostatic compression.
