Dear VASP support team,

I have read VASP manual and I did not find any mention of a tag in order to make a scissor operator or rigid shift to the band gap.
Is there in VASP any implementation of this shift mentioned above or similar?

Thank you in advance.

there is nothing like a 'scissors operator' (like eg defined by Fritsche et al) in VASP. For some systems with strongly correlated electrons, L(S)DA+U can be applied to increase the band gap width.
