Work functions of some metals (Mg, Mn, Cr, Bi, Cd, Pb, Te, Zn, and Sn) have been determined by using the zero‐bias internal‐voltage technique in asymmetric electrodes structures of metal/insulator/metal systems. The built‐up Langmuir films of barium‐stearate have been used as an insu...
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......
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...
What are Some Examples of Work Functions? The table below shows some examples of work function values for various metals and materials at room temperature. Molybdenum) | 4.6 | | Ru (Ruthenium) | 4.7 | | Rh (Rhodium) | 4.98 | | Hf (Hafnium) | 3.9 | | Ta (Tantalum) | 4.25 | | ...
The work function of metals is lowered upon alkali-metal adsorption and this lowering (ΔΦ) is known to be coverage dependent. Using standard jellium-model calculations, we show that if the metal-overlayer distance is assumed to increase with coverage, the experimental behavior of ΔΦ is much...
(a) Calculated work function values of metals on EG and b) the difference between calculated and reported work function values. A red dotted line indicates ΦC = ΦR. The low work function metals show consistently higher measured values than the values reported in the literature. Pr and...
Relation between conduction property and work function of contact metal in carbon nanotube field-effect transistors a nanotube quasi-pn diode with no impurity doping, in which different contact metals with different work functions are used for the anode and the cathode... Y Nosho,Y Ohno,S ...
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)...
By consideration of the Koopmans theorem expression for the work function of a metal, we find that the total height of the surface barrier potential equals the value of the bulk-plasmon energy of pure metals. As a consequence a simple formula for the work function is obtained which shows bett...
