Concentration-Dependent Surface-State Shifts: Au on Cu(001)
Published online by Cambridge University Press: 15 February 2011
Abstract
High-resolution angle-resolved photoemission has been used to investigate the behavior of the Cu(001) surface state as a function of Au coverage and substrate temperature. Binding-energy shifts of this state are dependent on the concentration of Au atoms substituted into the top surface layer of the Cu(001) substrate. The results demonstrate the use of surfacelocalized Tamm states as a specific probe of the chemical environment in the surface plane.
