      abstract     = {Employing first-principles calculations, we studied the
                      electronic structure of ultrathin Bi-Sb films, focusing on
                      the appearance of surface or edge states that are
                      topologically protected. Our calculations show that in
                      ordered structures the Bi-Sb bonds are quite strong, forming
                      well-defined double layers that contain both elements. We
                      find surface states appearing on the (111) surface of a thin
                      film of layerwise ordered Bi-Sb compound, while thin films
                      in (110) orientation are insulating. In the gap of this
                      insulator, edge states can be found in a (110)-oriented
                      ribbon in the A17 (black phosphorus) structure. While these
                      states are strongly spin polarized, their topological
                      properties are found to be trivial. In all structures, we
                      investigate the influence of spin-orbit coupling and analyze
                      spin polarization of the states at the boundaries of the
                      material.},
