Description: Bandstructure for Si within DFT+HF

Mind: For PBE bandstructure refer to Fcc Si bandstructure example.


  • INCAR
## Do a HSE hybrid functional banstructure
## calculation with (i) the KPOINTS.HSE.G-X file
## and (2) using VASP2WANNIER90
## Better first preconverge with DFT and then
## restart with the settings below!

## Default       
ISMEAR =  0
SIGMA  =  0.01
GGA    = PE

## HSE
#LHFCALC = .TRUE. ; HFSCREEN = 0.2 ; AEXX = 0.25
#ALGO = D ; TIME = 0.4 ; LDIAG = .TRUE.

##VASP2WANNIER
#LWANNIER90=.TRUE.
