Adlayer core-level shifts of random metal overlayers on transition-metal substrates

M. V. Ganduglia-Pirovano, J. Kudrnovsky, M. Scheffler

We calculate the difference of the ionization energies of a core-electron of a surface alloy, i.e., a B-atom in a A_(1-x) B_x overlayer on a fcc-B(001)-substrate, and a core-electr…
