The Characteristics of Chemisorptions on Si (001) Surface

Abstract:

The characteristics of chemisorptions, such as the pseudogap, forbidden bandwidth, energy curve, the trend of Fermi level in the graphics and the density of states at the Fermi level and so on, were given for the chemisorptions of atom on the Si (001) surface from the density of states. From these densities of states’ curves, the characteristics of chemisorptions were analyzed and compared to for different elements absorption on the Si (001) surface. The density of states for chemisorptions is different for the different elements.
