3D atomic structure of initial Li-X doped ZnO (LXZO) geometries. Grey (red) balls indicate Zn (O) atoms. Labels Li and X and correspondingly light grey and blue spheres identify the different dopant chemical species. VO and VZn hosts are obtained by removing the atoms marked by the circle and the star, respectively; Vdim host results from the removal of both atoms.
