Work function of refractory metals and its dependence upon working conditions To investigate the stability of work function ( φ ) of polycrystalline refractory metals (Nb, Mo, Ta, W and Re), the thermal electron current ( J ) from a......
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...
Treating the metallic sample as a semi-infinite jellium, the work function may be expressed by an equation, where the local density approximation (LDA) is accepted. This expression consists of two terms. The first term "the surface dipole barrier" depends on the electron density profile n(x)...

Ex49 功函数(work function)的计算(一) 前面我们讲完了表面的计算,后面两节我们主要讨论一下功函数的计算。 1 功函数的定义 首先,我们先看一下维基百科的解释: 功函数(又称功函、逸出功)是指要使一粒电子立即从固体表面中逸出,所必须提供的最小能量(通常以电子伏特为单位)。这里“立即”一词表示最终电子位置...
Work function, electronegativity, and electrochemical behaviour of metals. II. Potentials of zero charge and "electrochemical" work functions Preferred values of , work function, and E z, potential of zero charge, for metals have been collected through a critical examination of much experimental data...
