Band gap characterization of ternary BB1-xNx (0 <= x <= 1) alloys using modified Becke-Johnson (mBJ) potential

The semi-local Becke-Johnson (BJ) exchange-correlation potential and its modified form proposed by Tran and Blaha have attracted a lot of interest recently because of the surprisingly accurate band gaps they can deliver for many semiconductors and insulators (e.g., sp semiconductors, noble-gas solids, and transition-metal oxides). The structural and electronic properties of ternary alloys BB1 (-) N-x(x) (0
