Fermi Energy Shifting
« on: January 11, 2011, 12:10 »
By  calculating band structure of ZnO using VNL, I got band structrue in which energy is distributed from negative to positive and 0 energy is in between them. Fermi energy is negative nearly -4.02.

Please tell me that in the result browser's output band structure figure, 0 energy corresponds to fermi energy or value at -4.02 is femi energy?

If it is at -4.02 than I must shift whole band structure by setting fermi energy 0.

Unless you changed any advanced options, the Fermi level is the zero energy in the band structure.

Since ZnO is a semiconductor,  the Fermi level of ZnO is usually and physically set as the valence band maximum.

I am using ATK + VNL 2008.10 version. There is no such advanced option
