Iuliacumite: a novel two-dimensional chemical short range order in a wurtzite single monolayer InAs 1-x Sb x shell on InAs nanowires
Résumé
A chemical short range order is found in single monolayer InAs1-xSbx 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 ordering vector in [0001] and an anti-ordering vector in 1120 direction and arises from strong Sb-Sb repulsive interactions along the atomic chains in 1120 direction.
