Default: HFSCREEN = none
Description: HFSCREEN (in Å-1) specifies the range-separation parameter in range separated hybrid functionals.
In case LHFCALC=.TRUE., in combination with PBE potentials (or GGA=PE), attributing a value to HFSCREEN will switch from the PBE0 functional to e.g., the closely related HSE03 (HFSCREEN=0.3) or HSE06 (HFSCREEN=0.2) functionals.
