The fermi energy
Posted: Tue Nov 09, 2010 10:22 am
Hi every body
I want to know why in many band structure graphs or DOS graphs they do not put the exacte value of Fermi energy but they put the origin on it ? Could the Fermi energy of an element change from an occupation scheme to an another or from a calculation framework to another (for exemple : from ncpsp to paw)?
