State of the conduction electrons and the work function of a metal
Physics-Uspekhi, 1994The condition for a minimum of the bulk energy of a metal is used to determine the chemical potential of the conduction electrons. This potential is measured from the value of the energy far from the metal and is equal (with the opposite sign) to its work function.

Electron work function in alloys with alkali metals
Technical Physics, 2012The electron work function in alloys and compounds containing alkali metals, which are of interest for the designing of new photocathode materials and further development of the theory of electron emission, is studied. It is shown that a number of applied and theoretical issues in this field are poorly understood.

Macroscopic theory of the electron work function in solids
Philosophical Magazine, 2014The approach is based on the dielectric formalism theory. The relations for calculation of the electron work function in solids – metals, semiconductors and dielectrics, were obtained. The calculated results are in an agreement with experimental ones. This approach can be used for computation of work function values of numerous materials.

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 ...

The role of the electronic work function in electrochemical kinetics
Electrochimica Acta, 1968Abstract It is shown that the electronic work function, known to have no influence on electrode kinetics at metal/solution interfaces is however of importance in electrode kinetics at semiconductor/solution interfaces. The Bronsted rule for processes at semiconductor/solution interfaces is also discussed.

Calculation of the electron work function at metal surfaces by a density functional method
Russian Physics Journal, 1998We develop a method for calculating the electron work function on the surface of both simple and transition metals, using electronic density functional theory. We include corrections due to inhomogeneities in the electron density, the effects of surface relaxation in the ionic plane, and the electron-ion interaction, for which we use a generalized ...

The electronic work function of the different faces of tungsten
Surface Science, 1978Abstract We present a semi-empirical theory of the electronic work function of the different faces of tungsten. All the parameters entering the theory, except one, are estimated independently. The one adjustable parameter relates to the isotropic contribution to the work function, and, can, in principle, be determined from a self-consistent ...

Work function mapping of MoOx thin-films for application in electronic devices
Ultramicroscopy, 2017The knowledge of the structural and electronic surface morphology is imperative to fully understand the charge transfer at interfaces of electronic devices, such as in photovoltaic (PV) cells. To this aim, here, we use low-energy electron microscopy to probe the unoccupied states of post-annealed MoOx thin-films grown in oxygen excess (x∼3.16) and ...

A study on the kinetic response of the electron work function to wear
Wear, 2003The history prior to the onset of wear is of importance to fundamental understanding of tribological phenomena. In particular, diagnosis of wear under light loads has attracted increasing interest from the nano/micro-device industry. For a micro-device, it is difficult to use traditional wear testers to investigate its wear behavior due to limited ...
