(a) Calculated DOS of the top surface layer of the Sb40 (blue curve) and Sb41 (red curve) models. The black curve corresponds to DOS of unrelaxed Sb41 (unreconstructed monolayer-terminated Sb(111) surface with dangling covalent bonds) (b) Tunneling spectra of two non-equivalent surface regions, obtained at the blue and red crosses in Fig. 6c.
