<div dir="ltr"><div>Dear CP2K Users,</div><div><br></div><div>I am calculate the DOS for a crystal structure. It is a insulator. The density of state was found at Fermi energy level as shown in attached picture. I was really confused by the results. The DOS should be 0 at Fermi energy level. Even though the plots was broadening using deskinsgroup code, but that will just cause a slightly shifting above the Fermi energy level. Could anyone help me on the results? Any problem with the input? </div><div><br></div><div>Please see the attached settings for DFT section.</div><div><br></div><div><div> &DFT</div><div>  BASIS_SET_FILE_NAME BASIS_MOLOPT</div><div>  POTENTIAL_FILE_NAME GTH_POTENTIALS</div><div>  CHARGE 0</div><div>  MULTIPLICITY 1</div><div>  UKS TRUE</div><div>  &QS</div><div>   EPS_DEFAULT 1.0E-14</div><div>  &END QS</div><div>  &MGRID</div><div>   CUTOFF 400</div><div>   NGRIDS 4</div><div>   REL_CUTOFF 60</div><div>  &END MGRID</div><div>  &SCF</div><div>   SCF_GUESS RESTART</div><div>   EPS_SCF 1.0E-07</div><div>   MAX_SCF 1000</div><div>   &OT TRUE</div><div>    PRECONDITIONER FULL_ALL</div><div>    MINIMIZER CG</div><div>    ENERGY_GAP 0.001</div><div>   &END OT</div><div>   &PRINT</div><div>    &RESTART OFF</div><div>    &END RESTART</div><div>   &END PRINT</div><div>  &END SCF</div><div>  &XC</div><div>   &XC_FUNCTIONAL PBE</div><div>   &END XC_FUNCTIONAL</div><div>     &VDW_POTENTIAL</div><div>      DISPERSION_FUNCTIONAL PAIR_POTENTIAL</div><div>       &PAIR_POTENTIAL</div><div>       TYPE DFTD3</div><div>       REFERENCE_FUNCTIONAL PBE</div><div>       PARAMETER_FILE_NAME dftd3.dat</div><div>       R_CUTOFF 10.0</div><div>       &END PAIR_POTENTIAL</div><div>     &END VDW_POTENTIAL</div><div>  &END XC</div><div>  &PRINT</div><div>     &PDOS</div><div>      NLUMO -1</div><div>      COMPONENTS TRUE</div><div>      &LDOS</div><div>        COMPONENTS TRUE</div><div>        LIST 1..486   </div><div>      &END LDOS</div><div>     &END</div><div>   &END PRINT<br></div><div> &END DFT</div></div><div><br></div><div>Best regards,</div></div>
