Using the first principle methods, the electronic structure and magnetic properties of Co doped ZnO are investigated. It is found that Co substitutes Zn site in the host, and this doped configuration favors the ferromagnetic ground state. Electronic structure calculation shows that total magnetic moment for the supercell is 3.03 µB, which is mainly, contributed by Dopant (Co) 2.45 µB. The compound is found to be a semiconductor, where the filled-states are located in the valence bands and the empty ones above the conduction band edge. The filled and empty d-states are also shown to shift downwards and upwards in the valence and the conduction bands, respectively. The total and atom resolved density of states shed light on the evolution of the electronic and magnetic properties. |
