Nisi work function
WebApr 19, 2011 · The thermodynamic analysis shows that chlorine at the surface lowers the surface energy. We find that Cl can reduce the work function of NiSi by as much as ∼100 meV, and that the Schottky barrier with Si strongly depends on the position of the substitutional chlorine. WebMar 21, 2005 · Although a linear relationship between work function and Ni percentage was observed for FUSI of undoped poly-Si systems, the work functions of doped Co/sub x/Ni/sub 1-x/Si/sub 2/ are almost identical to those of doped NiSi FUSI metal gates.
