ABSTRACTWe investigate the electronic structure of interstitial Li and Li vacancy in Li7P3S11 by first principles calculations. We find that Li7P3S11 is a good insulator with a wide band gap of 3.5 eV. We find that the Li vacancy and interstitial Li+ ion do not introduce states in the band gap hence they do not deteriorate the electronic properties of Li7P3S11. The calculated formation energies of Li vacancies are much larger than those of Li interstitials, indicating that the ion conductivity may arise from the migration of interstitial Li.

The In1-xGaxN electronic structure is calculated by First principle based on density functional theory. The energy band structures and density of state is calculated. It can be found that the hybridization of the Ga4s4p and N2p,In5s5p is stronger than that of N2p,In5s5p in the undoped system. And it leads to the valence band moving towards to low energy level and the conduction band moving to the high energy level. Correspondingly, we can find a larger band gap than that of undoped InN. In conclusion, the wide band gap lead to the blue shift and Moss-Burstein effect occurs near the top valence band.
