Based on the thermionic emission theory, a method to extract parameters of Si SBD is given in this study. Using this model, we tested the characteristics of devices and extracted the parameters of two kinds of samples. The ideality factor is 1.01 and 2.13 respectively. The zero-field barrier height is 0.70eV and 0.72eV. The surface state density is 5.5×10~(15)cm~(-2)eV~(-1) and 4.3×10~(12)cm~(-2)eV~(-1). The interface oxide capacitance is 9.0×10~(-4)F·cm~(-2) and 5.4×10~(-6)F·cm~(-2). The neutral level of the surface states is 0.81eV and 1.1eV. The reverse breakdown voltage is 101V and 56V.

The adsorptions of SiH_2, SiH_2 with a hydrogen adatom (SiH_2+H) and SiH_2 with two hydrogen adatoms (SiH_2+2H) on the Si (100) surface near SDV structure have been calculated. Three possible sites are found in each case, and the presenting of hydrogen may reverse the relative stability of these sites.
