A certain number of hybrid functionals are available in VASP. For some of them, it is shown how to specify them in the INCAR file:

LHFCALC  = .TRUE.
HFSCREEN = 0.3 
with the default values AEXX=0.25, AGGAX=1-AEXX=0.75, AGGAC=1.0 and ALDAC=1.0, and using the PBE POTCAR files or with the following additional entry:
GGA = PE

LHFCALC  = .TRUE.
HFSCREEN = 0.2 
with the default values AEXX=0.25, AGGAX=1-AEXX=0.75, AGGAC=1.0 and ALDAC=1.0, and using the PBE POTCAR files or with the following additional entry:
GGA = PE

  • PBE0
LHFCALC = .TRUE.
with the default values AEXX=0.25, AGGAX=1-AEXX=0.75, AGGAC=1.0 and ALDAC=1.0, and using the PBE POTCAR files or with the following additional entry:
GGA = PE
  • B3LYP
LHFCALC = .TRUE. 
GGA     = B3 
AEXX    = 0.2
AGGAX   = 0.72 
AGGAC   = 0.81 
ALDAC   = 0.19
and using PBE POTCAR files
  • Hartree-Fock
LHFCALC = .TRUE. 
AEXX    = 1.0
ALDAC   = 0.0 
AGGAC   = 0.0
With the default: AGGAX=1-AEXX=0.0, and using the PBE POTCAR files.
