[Pw_forum] DOS of graphene

[ehsan targholi]

hi
Dear all
i calculate DOS of graphene but my DOS is not compatible with reference. in
the reference, DOS of graphene is U-shaped with minimum at 0 eV but in my
calculation this minimum occure at -.35 eV.  i increase K-point to 48 48 1
and change pseudopotentials. but result not change.
DOS of my calculation is attached,

besst regard
