Sm-N共掺杂对锐钛矿相TiO2的电子结构和吸收光谱影响的第一性原理研究
First-principles study on the electronic structures and absorption spectra of Sm-N codoped anatase TiO2
摘要
Abstract
Based on first principles within density-functional theory, we establish three models of N doped anatase TiO2, Sm doped anatase TiO2 and Sm-N codoped anatase TiO2 by using the plane-wave ultrasoft pseudopotential method. We calculate their densities of states, band structures and absorption spectra. Their results show that although the N doped anatase TiO2 takes the best redshift, the Sm-N codoped anatase TiO2 makes better lifespan of electron and the Sm-N codoped anatase TiO2 is more stable.关键词
