INCAR

general:
  SYSTEM = Graphite surface slap
  ENMAX  = 400
  ISMEAR =    2  ; SIGMA = 0.2
  ALGO = Fast

partial charge densities:
  LPARD = .TRUE.
  LSEPK = .FALSE.
  LSEPB = .FALSE.
  NBMOD = -3
  EINT = -0.1 0.1
 
# DOS:
#   ISTART = 0
#   ICHARG = 2
#   LORBIT = 11

KPOINTS

K-Points
0
Monkhorst-Pack
9 9 1
0 0 0

• Only one k point in z direction since we have a surface.

Calculation

• First copy INCAR.DOS to INCAR to get the lm-decomposed DOS.

• Second copy INCAR.par to INCAR and run VASP for the preliminary calculation.

• To get an STM image use p4vasp:
