Dustin A. Hite, Hossein Jooya, Kyle S. McKay, Eunja Kim, Philippe F. Weck, David P. Pappas, H.R. Sadeghpour

The variation of the work function upon carbon adsorption on the reconstructed Au(110) surface is measured experimentally and compared to density functional

Electric- field noise from carbon-adatom diffusion on a Au(110) surface: first-principles calculations and experiments
