<div dir="ltr">Dear All.<div><br></div><div>I have tried to calculate the band gap of Ta3N5. When I use the primitive cell with 16 atoms I obtain a band gap of 1.68 eV at the Gamma point; however, when I use the conventional cell with 32 atoms, I find a band gap of 1.34 eV at the Gamma point. I have already checked the convergence of both calculations with respect to the energy cutoff and the k-point grid. </div><div><br></div><div>I was wondering if this could be related to the Brillouin zone folding. Do anyone have any idea why I obtain too different values at the same point? </div><div><br></div><div>I will really appreciate any help in this issue. </div><div><br></div><div>Best wishes,</div><div><br></div><div>Juliana Morbec</div><div><div><div dir="ltr"><div>-----<br></div>Juliana M.
