✦ Synopsis

It is proposed that surfaces of crystals which reconstruct with broken orientational symmetry and ex- hibit an anisotropic intrinsic stress tensor are unstable to the formation of elastic-stress domains. Thus the ground state of suck a surface is not uniform, contrary to previous expectations. Evidence of this for the Si(001) surface is discussed.
