Abstract: Antimony ultra-thin films in tensile strain are grown on InAs(111)B substrates and studied in situ using surface X-ray diffraction. The detailed atomic structures of two highly crystalline Sb(0001) films are derived, with thicknesses of 19 and 4 bilayers. Features considered in structural modelling include interfacial intermixing, surface roughness, individual layer relaxations and rotational twin domains (RTDs). The 4-bilayer film shows significant structural relaxation in every layer, while both films include RTDs. The results are discussed in relation to the topological properties of low-dimensional Sb.
