چکیده انگلیسی
Various adsorbates prefer commonly 2 Ã 2 translational symmetry on Si(1 1 3), whose structure models were suggested to be composed of one-dimensional (1D) atomic chains, aligned along [11¯0], of adatoms and tetramers (or pentramers). We characterized clearly the electronic structures of the 1D chains using the Sb-decorated Si(1 1 3)2 Ã 2 surface. The 1D chains on Sb/Si(1 1 3)2 Ã 2 were found to produce three energy bands with binding energies of 1.0, 1.4, and 1.75 eV at the normal emission by angle-resolved photoemission spectroscopy experiments. The three bands show interesting dimensional characters; the two energy bands with binding energies of 1.0 and 1.4 eV are close to ideal 1D ones in comparison with the other close to a quasi 1D one. In this report, we will describe the 1D energy bands on the bases of the 1D atomic chains.
