The type of material:Different materials have different electronic structures and bonding energies, which affect their ability to hold or release electrons. Generally, metals have lower work functions than non-metals, because metals have more free electrons that can be easily removed from their 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 surface and the bulk. Accurate face-dependent work functions are ...
Anisotropy in the electronic work function of crystals of 3d metals An expression for the analytical relation between the surface energies and electronic work functions of the faces of a metallic crystal is obtained using a... IG Shebzukhova,LP Aref’Eva - 《Bulletin of the Russian Academy of...
water splittingPhotocatalytic water splitting was performed on TiO2 and metal-containing TiO2 (MTiO 2) catalysts under UV light irradiation. TiO2 was added with various metals of different work functions, namely, Pt (5.93 eV), Pd (5.60 eV), Cu (5.10 eV), Ru (4.71 eV), and Ag (4.26 eV...
Schottky barrier height dependence on the metal work function for p-type 4H-silicon carbide We investigated Schottky barrier diodes of several metals (Ti, Ni, and Au) having different metal work functions to p-type 4HSiC (0001) using I–V and C–V... SK Lee,CM Zetterling,M ?Stling -...
metals and their metallic derivatives are attractive candidates, there are numerous process integration challenges that must be overcome before a viable metal-gate CMOS technology can be developed. This paper highlights some of these challenges and reviews ...
Anisotropy of the Electronic Work Function of Metals Work function is experimentally known to be different for different faces of a crystal by amounts ranging from one-tenth to half a volt. For tungsten the faces can be arranged according to decreasing work function as follows: 110, 211, 1....
X70-30Ni has two different groups of domains with different work functions. (e) CPS ~ binding energy curves of X70, X70- 10Ni and X70-70Ni. The area under a curve is proportional to the number of free electrons in the sample. The number of free electrons is highest for X70-10Ni, ...
The results are in excellent agreement with a recent full-potential, all-electron, slab-supercell calculation of surface energies and work functions for the 4d metals. The present calculations explain the trend exhibited by the surface energies of the alkali, alkaline earth, divalent rare-earth, ...
