BookDOI
Photoelectron spectroscopy : principles and applications
TL;DR: In this paper, the three low-index faces of a Face-Centered Cubic (fcc) Crystal Face were modeled as 3D cubic faces, and a table of binding energies was presented.
Journal ArticleDOI
Direct measurements of the L -gap surface states on the (111) face of noble metals by photoelectron spectroscopy
TL;DR: In this article, the L-gap surface states of the (111) surfaces of Cu, Ag, and Au were studied by high-resolution angle-resolved photoelectron spectroscopy (PES).
Journal ArticleDOI
Spin-orbit splitting of the L -gap surface state on Au(111) and Ag(111)
TL;DR: In this article, high-resolution photoemission results on the L-gap surface state on Au(111) and Ag(111), in combination with fully relativistic density functional calculations are presented.
Journal ArticleDOI
Photoemission spectroscopy—from early days to recent applications
Friedrich Reinert,Stefan Hüfner +1 more
TL;DR: In this article, the authors describe the development of photoemission spectroscopy (PES) from the first historic observations of the photoelectric effect by Hertz and Hallwachs to state-of-the-art experiments.
Journal ArticleDOI
Electronic structure of 3d-transition-metal oxides: on-site Coulomb repulsion versus covalency
TL;DR: In this paper, the photoemission core-level spectra are analyzed in terms of a simple cluster model leading to estimates for the charge-transfer energy, the Coulomb correlation energy, and the hybridization strength V. This trend is attributed mostly to the increasing number of empty d states in the early transition metals which enhances the effective metal-ligand hybridization.
