I am a beginner of Quantum Espresso. I have taken 221 MoS2 Monolayer and done a relax calculation.
In case of bulk system, or any doping in supercell, which is preferred:
It's not clear to me under what conditions I need to use one vs the other.
Before the relax calculation, I converged ecutwfc, k-points and ecutrho (using ultrasoft pseudopotential). Do any other parameters have to converge before starting this type of calculation?
