density of state of single-layer graphene

[PhyChemKang]

Hi communitors

Recently, i calculated single-layer graphene with VASP

The all calculations for SLG showed the 0 density state in

Fermi level. However, i obtained the different result with

others and i can't not understand what is the problem.

Thus, i'm asking you guys to solve this problem.

Could you someone help me??

I upload the cartesian coordinate and detail calculation setup
