Could it be due to the broadening in <a href="http://case.int" rel="noreferrer" target="_blank">case.int</a>? Try to execute tetra with a reduced (or no) broadening.<br>

Subject: [Wien] Confusion about DOS<br>
<br>
Dear Wien2k users,<br>
<br>
I have plotted DOS for material with converged SCF using HSE06. I got a bandgap of 2,875 eV. However, in the plotted DOS it can be seen that a small amount of DOS from the valence band is crossing the Fermi energy. I have attached the plot to this mail.<br>
<br>
Is this crossing can be neglected or I should have to change some other parameters like broadening etc.<br>
<br>
with regards,<br>
<br>
