Abstract

A chemical short-range order is found in single monolayer InAs_1-xSb_x shells, which inherit a wurtzite structure from the underlying InAs nanowire, instead of crystallizing in the energetically preferred zincblende structure. The chemical order is characterized by an anticorrelation ordering vector in the ⟨112̅0⟩ direction and arises from strong Sb-Sb repulsive interactions along the atomic chains in the ⟨112̅0⟩ direction.

Keywords: Chemical ordering; In(As,Sb); nanowire shell; single monolayer; wurtzite.
