[Pw_forum] DOS of graphene

[ehsan targholi]

hi
Dear all
i calculate DOS of graphene and divide DOS to area of my supercell. and
give the DOS in unit of 1/eV.(angstrom)^2
 but my result is not compatible with reference.
i use of   smearing='fermi-dirac' & degauss=0.0005D0 & k-point = 24*24*1
what is wrong in my work?

in attached file: red line is my result and black line is reference.


best regard
