Effects of dopants and excess silicon on the oxidation of

Excess silicon in the silicide retards the oxidation. These phenomena can be explained by a mechanism in which the kinetics is controlled by the silicon out‐diffusion through the silicide. Analogous to crystalline silicon, the oxidation rate can be enhanced by high concentration of dopants which create point defects that aid the silicon Get price
