摘要：

The optical technique of reflection anisotropy spectroscopy (RAS) has been used to study the Cu(110)(1 x 2) surface reconstruction induced by Na adsorption. Room temperature deposition of submonolayer coverages of Na onto the Cu(110) surface results in the (1 x 2) reconstruction and is known to induce energy shifts in both the occupied and unoccupied surface states at the (Y) over bar point on Cu(110). Transitions between these surface states have been associated with a peak observed at 2.1 eV in the RA spectrum. We report RAS studies of the reconstruction and relate changes in the RA spectra at 2.1 eV to changes in the surface states induced by Na adsorption.
