Tunable ionic and electronic conduction of lithium nitride via phosphorus and arsenic substitution : a first-principles study by Wu, Shunnian, Neo, Su San, Dong, Zhili, Boey, Freddy Yin Chiang, Wu, Ping

“…But a full substitution of P and As results in variation of crystal structure from the space group P6/mmm to P63/mmc, and the energy band gaps of Li3P and Li3As are reduced to 0.72 and 0.65 eV, respectively, in comparison with 1.14 eV of Li3N. …”
