Abstract
Ab initio pseudopotential calculations are performed to investigate the geometry, electronic structure and orbital characteristics of the high index Si(1 1 4)-c(2 × 2) surface. It is found that there are several states in and around the band gap of bulk silicon and that the surface is characterised by a small band gap of approximately 0.1 eV within the local density approximation.
