Abstract

The carbon impurities significantly changed the scanning tunneling spectroscopic signature of the 3d-surface state of V(001). Band structure revealed that the observed surface state near the Fermi level has d_z² symmetry and disperses downwards around the center of the surface Brillouin zone. The upward peak shift cannot be described in terms of confinement. The effect was brought by the large impact of the vanadium surface s-d interactions on the surface state energy which changed upon carbon coverage.
