The work function is important property of a crystal surface. This article discusses definition and different kinds of the work function. The polycrystalline work function not only controls the ability of electrons to escape the crystal but also correlates with the chemical properties of both the ...
The work function of the emitter and the threshold wavelength are View Solution The work function of a metal is 4.2eV. If radiation of 2000Å fall on the metal then the kinetic energy of the fastest photoelectron is View Solution The work function of two metals metal A and metal B ...
A light of wavelength 600 nm is incident on a metal surface. When light of wavelength 400 nm is incident, the maximum kinetic energy of the emitted photoelectrons is doubled. The work function of the metals is View Solution Work function of a metal is 4.0 eV. Its threshold wavelength wi...
摘要: The Schottky model is extended through the use of the Thomas-Fermi approximation; the relevant differential equation for the electric scalar potential is solved and through it an estimate of the work function for metals is obtained.
It has been shown that there is a very highly significant correlation coefficient between the work function (Φ) of metals and the activation energy for oxidation (E). The values of Φ-E tend to decrease slightly with increase in the atomic number.doi:10.1002/recl.19530720903...

Metal films deposited on graphene are known to influence its electronic properties, but little is known about graphene’s interactions with very low work function rare earth metals. Here we report on the work functions of a wide range of metals deposited on n-type epitaxial graphene (EG) as ...
Work Function of Metals The Definition of Work Function The work function is one of the most important physical properties of a crystal surface.1 The electronic work function is a positive quantity (the concept of work function applies also to positron for which it can take negative values), ...
