Jellium work function for all electron densities
Physical Review B, 1988The work function and surface energy of jellium have been calculated for low (${r}_{s}$=12), metallic (2\ensuremath{\le}${r}_{s}$\ensuremath{\le}6), and high (0.5\ensuremath{\le}${r}_{s}$\ensuremath{\le}2) bulk electron densities. As the density increases, the work function peaks at 3.8 eV (${r}_{s}$=1.7), minimizes at 3.6 eV (${r}_{s}$=0.9, a density ...

Microstructure – electron work function relationship: A crucial step towards “electronic metallurgy”
Materials Today Communications, 2021Abstract Electron work function (EWF) is a promising parameter for guiding structural materials design. This parameter is intrinsically correlated to the metallic bond strength and stability, on which mechanical and electrochemical properties of metals depend.

Low work function electron emitter hexaborides
Journal of Vacuum Science and Technology, 1978Desirable properties of potential electron emitter materials include a high melting point, low vapor pressure and compound stability at elevated temperatures, in addition to a favorable work function φ and Richardson number. The rare-earth hexaborides combine many of these properties.

Electron and positron work functions of Cr(100)
Surface Science, 1983Abstract We report measurements of the electron and positron work functions of submonolayer contaminated single crystal surfaces of Cr(100) in ultra high vacuum. The positron work function o + is obtained by measuring the spectrum of slow positrons reemitted by the Cr(100) surface when it is bombarded with keV energy positrons.

Electron work function: a novel probe for toughness
Physical Chemistry Chemical Physics, 2016Fracture toughness of transition metals can be correlated to the electron work function. Within the range where the electron work function is smaller than 4.6 eV, the fracture toughness increases with the electron work function. However, if the electron work function exceeds 4.6 eV, the fracture toughness decreases with an increase in electron work ...

Electron work function and electronic affinity of intrinsic semiconductors
Soviet Physics Journal, 1985By using the simplest dielectric permittivity models, relationships are obtained on the basis of a dielectric formalism, by which the electron work function and electronic affinity of polycrystalline materials—metals, intrinsic semiconductors, and dielectrics—can be estimated.

Electronic Work Function of Potassium–Cesium Alloys
Russian Journal of Electrochemistry, 2002The temperature and concentration dependences of the electronic work function (EWF) of K–Cs alloys at thermodynamic equilibrium in an ultrahigh vacuum are studied with a photoelectric method. At 0–20 and 70–100 at. % Cs, the temperature coefficient of EWF depends on the Cs concentration cCs in a complicated fashion: it is positive at small cCs and ...

Electron work function of Rb-Cs alloys
Technical Physics, 2006The temperature and concentration dependences of the electron work function (EWF) of rubidium, cesium, and nine Rb-Cs alloys are studied by the Fowler photoelectric method under the conditions of an ultra-high vacuum. It is shown that the polytherms of the electron work function for the pure components and alloys decrease by a linear law with ...

Dimensional effect of work function of electrons
Nanotechnologies in Russia, 2008For ultrathin carbon films with controllable graphite nanophase contents, direct experimental evidence is found that the work function of electrons decreases with reduction of characteristic dimensions (thickness). The observed effect is associated with the splitting of the electron states in ultrathin films, as in the 2D quantum well.

Tailoring M7C3 carbide via electron work function-guided modification
Scripta Materialia, 2021Abstract M7C3 carbide [M: metallic element] is the primary reinforcement in white cast irons. Further improving its properties for maximized benefits is highly desired. However, no clear clues are available to guide the modification. Through atomic force microscopy in-situ analysis and first-principles calculations, we demonstrate that (Fe,Cr)7C3 ...
