But when I plot it with plotband.x, the Fermi level is exactly at the middle of the forbidden gap.<br>I think as a conductor, the Fermi level should be in the conduction band.<br>Has something gone wrong?<br><br>Thanks for your help<br><br><br><br>******************************************<br>Bertrand SITAMTZE YOUMBI<br>Laboratory of Material sciences<br>Department of physics<br>University of Yaoundé I-Cameroon<br>PO Box 812 Yaoundé-Cameroon<br>********************************************<br><br></td></tr></table><br>
