The work function of the elements and its periodicity
TLDR
In the data for the 63 elements, trends that occur simultaneously in both the columns and the rows of the periodic table are shown to be useful in predicting correct values and also for identifying questionable data.Abstract:
A new compilation, based on a literature search for the period 1969–1976, is made of experimental data on the work function. For these 44 elements, preferred values are selected on the basis of valid experimental conditions. Older values, which are widely accepted, are given for 19 other elements on which there is no recent literature, and are so identified. In the data for the 63 elements, trends that occur simultaneously in both the columns and the rows of the periodic table are shown to be useful in predicting correct values and also for identifying questionable data. Several illustrative examples are given, including verifications of predictions published in 1950.read more

Evidence for strong Fermi-level pinning due to metal-induced gap states at metal/germanium interface
TL;DR: In this article, Ohmic and Schottky properties of metal/germanium (Ge) junction have been investigated and it has been shown that Fermi level at metal/Ge interface is intrinsically pinned at the charge neutrality level (CNL) characterized by the metal-induced gap states model.

CO adsorption on close-packed transition and noble metal surfaces: trends from ab initio calculations
TL;DR: In this paper, the trends in adsorption energy, geometry, vibrational properties, and other parameters derived from the electronic structure of the substrate were studied, and the influence of specific changes in their set-up, such as choice of the exchange correlation functional, the choice of pseudopotential, size of the basis set and substrate relaxation, has been carefully evaluated.

Image potential states on metal surfaces: binding energies and wave functions
TL;DR: In this article, a pseudopotential analysis of both surface and image potential states on simple metal surfaces is presented, where the local density approximation (LDA) is used to describe the one-electron potential inside the film and in the surface region.

Work Functions of the Elements
TL;DR: The work function φ is a periodic function of atomic number, as shown clearly by a new compilation of published data for 57 elements as mentioned in this paper, and the progressive rise and fall of work function values throughout the table of the elements appears to be sufficiently regular to permit approximations to be made of values for the metallic and semimetallic elements on which no data has yet been published.
