Abstract:In this paper, the electronic structure and optical properties of CdS doped by Sn with different concentrations were investigated by first principles. The calculation results of electronic structure show that the doping of Sn can produce a deep impurity level band in the band structure of CdS. The calculation results of optical property show that Sn doping can increase the light absorption coefficient and conductivity of CdS. The overall calculation results show that Sn doping can produce stable intermediate b… Show more
