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

Calculation

This example is carried out in complete analogy to the example STM of graphite.

The sample output for the graphite (left) and graphene (right) STM images should look like the following:
