Dear All,<br>I made a SiC/SiO2 structure with QE.<br>The code kept giving me "charge is wrong, smearing is needed", no matter what charges I used (even after correcting charges for several times.<br>This is why I used smearing with degauss=0.018.<br>
Now that I get a fermi level, I was wondering how to interpret it for a semiconductor system.<br>I guess that since the number of states in the gap is high,, the code considers it as a "metal system"; however, as I wrote, I don't know how to interpret the fermi level.<br>
I really appreciate your help and support.<br>Thanks in advance.<br>Yours<br>P Shok<br>UMD <br>
