- 論文の詳細を見る
The variation of band gap energy, band structure and lattice constant of mixed LiBaF3, LiCaF3 and LiSrF3 perovskites is studied. The band structure and transition type of these fluorides is predicted by ab initio band calculation based on the local density approximation. The design principle of vacuum ultraviolet light emitting diode is proposed. The lattice-matched double-hetero structure of different perovskite-like fluorides is found to be sufficiently feasible to fabricate with direct-band-gap compounds LiBaxCaySr(1-x-y)F3 on LiSrF3.
