| We treat the core states fully relativistically and the valence states scalar relativistically and use angular momenta up to l=8 in the muffin-tin spheres for both the wave functions and charge density in the self-consistent cycles. The energy cutoff for the plane-wave expansion in the interstitial region between the muffin-tin spheres is taken to be 20.25 Ry, and the muffin-tin radii employed are RN=1.4 Bohr for N and RTa=2.47 Bohr for Ta, except for the N interstitials and the Ta3N5 phase where, due to the smaller N-Ta distances£¬we used RTa=2.10 bohr and RTa=2.2 bohr, respectively.In the calculation of energy differences, we took care to use exactly the same plane-wave cutoff and muffin-tin radii and, as close as possible, k-point samplings. |
