Abstract

We have investigated the growth of Fe on Au(455) and Au(788) surfaces by scanning tunneling microscopy and examined the electronic structures by angle-resolved photoemission spectroscopy. We found that deposited Fe atoms adsorb at the lower corners of the steps, and form one-dimensional monatomic Fe chains. In addition, Fe deposition has significant influence on the surface potential of the regularly stepped surface. After decorating the step edges with monatomic Fe rows, photoemission spectra measured in the direction perpendicular to the steps show parabolic dispersion and a downward energy shift of the bottom of the surface state band. This result suggests that Fe adatoms at step edges act as attractive scatterers and reduce the step potential barrier height.
