WebOur calculation results showed that the band gap width of the CsI(Na) (010) surface decreased after adsorbing H 2 O molecules, while three new peaks appeared in the valence band, and the absorption coefficient decreased from 90,000 cm −1 to 65,000 cm −1, and the reflection coefficient decreased from 0.195 to 0.105. WebThis can be caused by both defects in the near-surface layer of the semiconductor and impurities contained in the dielectric layer, which can generate charge carriers. It was found that the near-surface layers of the barrier structures contain only one deep level in the silicon band gap, with an activation energy of Ev + 0.38 eV.
