Dear QE users,
I want to caluculate the electronic band structure of oxides with charged vacancies. So can you tell me how to assign charges to vacancies in QE?
Moreover, under the cyclic boundary conditions, the charged vancies will introduce the so called "image" Coulomb interaction between adjacent supercells? Does anybody how to remedy this fake potential in the total energy?
