(color online) Partial densities of states (pDOSs) of (a) V and (b) (2V–V that can be attributed to V (red) and V (blue), respectively. The DOS for bulk ZnO is also shown as shaded regions. The VBM is set to be zero value of energy. The bulk conduction band DOS and the partial DOS of the V are magnified by factors of 10 and 5, respectively. (c) A schematic drawing of the level repulsion between V and V. The pDOSs are obtained by projection onto the most adjacent Zn atoms for the V level and onto the most adjacent O atoms for the V level, respectively.[17]
