And it shows that the difference is due to the atomic like basis set of siesta.</div><div style="font-size:large;color:#20124d"><br></div><div style="font-size:large;color:#20124d">Now my question is that which bandstructures are more reliable? I guess that as the structure is periodic the planewave should give a better simulation; is it right?</div><div style="font-size:large;color:#20124d"><br></div><div style="font-size:large;color:#20124d">Best regards,</div><div style="font-size:large;color:#20124d">Zahra</div><div style="font-size:large;color:#20124d"> </div></div>
