The physical properties of Li-doped g-C3N4 monolayer sheet investigated by the first-principles
Source abstract
Abstract
Abstract The geometric, electronic, optical properties, thermodynamic stability, and work function of Li-doped g-C 3 N 4 monolayer were investigated by the first-principles calculation. It was found that the Li atoms were preferentially substituted the open-hollow sites of g-C 3 N 4 . Interestingly, the “odd” number of Li doped g-C 3 N 4 showed metallic properties, while the “even” number of Li atoms widened the band gap of g-C 3 N 4 . The HOMO and LUMO distributions reveal that the active sites located at edge N and C atoms for both pristine and the Li-doped g-C 3 N 4 . In addition, thermodynamic analysis showed that the doped Li atoms reduced the thermodynamic stability of g-C 3 N 4 monolayer sheets.
