Hi
I want to know if  espresso  can do charged vacancy calculation or not? I know about isolated atoms but I am not sure about big bulk supercell?
If it can, how we can put the charge on the right position of the vacancy(which constraint should we introduced)?
another question, Could anyone introduced me some reference about screening effect around the point defect?
thanks a lot
