摘要：

Angle-resolved photoemission spectroscopy (ARPES), using HeI radiation, has been used to probe the occupied electronic states from a single domain of the Au-induced 5 x 2 reconstruction of Si(lll), a quasi-one-dimensional (quasi-1D) metallic system. The ARPES spectra recorded parallel (perpendicular) to the Au chain structure show a signature of a metallic (non-metallic) system. These experimental results are intriguing since, for the first time, spectral intensity at the Fermi level is observed in a photoemission study of a quasi-1D metallic system.
