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.ANGLE-RESOLVED PHOTOEMISSIONELECTRICAL TRANSPORTGOLDLOW-ENERGYELECTRON DIFFRACTION (LEED)METAL-SEMICONDUCTOR INTERFACESPHOTOELECTRON EMISSIONSILICONSURFACE ELECTRONIC PHENOMENASURFACERELAXATION AND RECONSTRUCTIONVICINAL SINGLE CRYSTAL SURFACESSPECTRAL-FUNCTIONSURFACESENERGYSURFACESAngle-Resolved Photoemission from an Unusual Quasi-One-Dimensional Metallic System - a Single-Domain Au-Induced 5x2 Reconstruction of Si(111)text::journal::journal article::research article
