<div>Dear All</div>
<div> </div>
<div>I get positive fermi energy (+7.8 eV) for bulk graphite by Quantum Espresso. Positive energy is meaningless for me here. Would you please say me that in whcih way QE selects the zero energy?</div>
<div>As I know the vacuum should be considered as zero energy. I appreciate you in advance to solve the problem.<br clear="all"><br>-- <br>Sincerely Yours<br>David G.<br>JCU<br><br></div>
