The variation of the work function of nickel with temperature was measured with clean (111) and (100) surfaces between 25 and 320 °C and up to 430 °C with Ni(110). In all cases the work function decreases linearly with temperature by 1.7 x 10-4 eV/°C. No anomaly (neither a ...
The mechanism underlying the modulation of nickel fully silicided (Ni-FUSI) gate work functionΦmby rare-earth (RE)-based dielectric interlayers (RE: Y, Er, Dy, Tb, Yb, and La) was investigated. RE–O–Si bonding in these ultrathin(1nm)interlayers induces highly polarized RE–O bonds ...
A novel method of forming rare-earth (RE)-based interlayers to engineer the work function (Phi) of nickel fully silicided (Ni-FUSI) gates was investigated. An extensive range of RE metals comprising yttrium (Y), erbium (Er), dysprosium (Dy), terbium (Tb), gadolinium (Gd), ytterbium (...

This paper investigates the work function adjustment of Ni-FUSI metal gate by implanting Yb into poly-Si gate before silicidation. It is obvious that implanting Yb into poly-Si before silicidation can modulate the work function of Ni-FUSI metal gate efficiently and increasing dose can extend ...
Fracture-resistant ultralloys for space-power applications: Normal-spectral-emissivity and electron-emission studies of tungsten, rhenium, hafnium-carbide ... Effective work function ( φ e) is an important consideration in the selection of the electrode materials for high-temperature thermionic energy ...
Work function is a key concept in physics that describes the minimum energy needed to remove an electron from a solid surface. It has important applications in various fields, such as thermionic emission, photoelectric effect, field emission, and surface
The high-work-function and high-conductivity electrode may further include at least one of a metal nanowire, a semiconductor nanowire, a metal nanodot, graphene, reduced graphene oxide, and graphite. The metal nanowire may be selected from the group consisting of Ag, Au, Cu, Pt, nickel silic...
Charge transfer and positron states at alkali-metal-covered nickel surfaces With the lowering of the electron work function, this leads to positronium desorption energies which are weakly dependent on the alkali coverage, in agreement with the recent experiments of Gidley, K枚ymen, and Capehart. ...
