不同浓度C掺杂SnO2的第一性原理计算
First-principle study of C-doped SnO2 at different concentrations
摘要
Abstract
The crystal structures,band structures,densities of states and optical properties of different concentra-tions C-doped SnO2 are investigated by the first-principles calculation method based on density functional the-ory.The results show that the unit cell volume and lattice constants of the doping systems are slightly increased with the increasing doping concentration.The band gap of the band decreases as the concentration increases.From the calculation of the optical properties,the absorption edge of the system after doping C moves towards the low energy direction.With the increase of doping concentration,the redshift of the system is more obvious.关键词
