摘要: Using the scattering-theoretic method and employing the nearest-neighbor tight-binding formalism to describe the bulk electronic structure, we have studied the electronic structure of Si(337) surface. The wave-vector-resolved layer densities of states are presented. The results show that there are six surface bound states in the range from -12.0 to 2.0 eV. Some properties of these surface states are discussed.
