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:
