[Pw_forum] F centers in QE

[Amar Singh]

Dear Friends,​How can we represent F centers in a structure for QE calculations. F centers basically mean removing a oxygen from the structure and placing none, one or two electrons at the vacancy (respectively F+2, F+1 and F0 centers). As a result, the unit cell will have a net charge of +2, +1 and 0 respectively for F+2, F+1 and F0 centers.thanks
