In this article, the authors used the self-consistent screened Korringa-Kohn-Rostocker method to obtain the electronic structure of the Shockley-type surface states.Abstract:
The electronic structure of the $\mathrm{Cu}(332)$ and $\mathrm{Cu}(221)$ surfaces is obtained by the self-consistent screened Korringa-Kohn-Rostocker method. Angle-resolved photoemission spectroscopy (ARPES) spectra for the Shockley-type surface states at binding energies $\ensuremath{\leqslant}0.5\phantom{\rule{0.3em}{0ex}}\mathrm{eV}$ are calculated within the one-step formalism and found to be in good agreement with experimental data. There is a parabolic band, asymmetrically displaced to the boundary of the surface Brillouin zone. We show that the asymmetry occurs only in the ARPES spectra, whereas the underlying surface band structure is symmetric and explain the asymmetry of the ARPES spectra by analyzing the surface state wave function.read more

TL;DR: In this paper, an accurate momentum mapping of bulk and surface electronic states by angle-resolved two-photon photoemission is demonstrated on Cu(111) and one of its vicinal surfaces, Cu(443), using laser light of $3.08\phantom{\rule{0.3em}{0ex}}\mathrm{eV}$ photon energy for excitation.
