Self-consistent pseudopotential calculations have been performed to determine the electronicstructure of a Si overlayer on GaP(110) surface. The results show that both filled and empty Si-induced states appear in the gap. The consequences for the Fermi level pinning are discussed and recent experimental results are explained.
