hope you are doing well. I am trying to study the electronic properties of ZnO doped with transition metals (Co, Ni, Fe) using DFT calculation, I am a beginner on DFT calculation using quantum espresso. After running multiple test with increasing the 'ecutwfc' (kinetic energy cutoff for wavefunctions) and 'conv_thr' (convergence threshold) in my input files I get almost the same total energy.
I want to know please how can I make sure that my SCF calculation are correct?
Thank you for your help.
