Coupled Pb chains on Si(557): Origin of one-dimensional conductance


Tegenkamp, C; Ohta, T; Mc Chesney, J L; Dil, H; Rotenberg, E; Pfnür, H; Horn, K (2008). Coupled Pb chains on Si(557): Origin of one-dimensional conductance. Physical Review Letters, 100(7):076802.

Abstract

The Pb/Si(557) system exhibits a strong anisotropy in conductance below 78 K, with the evolution of a characteristic chain structure. Here we show, using angle-resolved photoemission, that chain ordering results in complete Fermi-like nesting in the direction normal to the chains; in addition, the domain structure along the chains forms split-off valence bands with mesoscopic Fermi wavelengths which induce the 1D conductance without further instabilities at low temperatures.
