Electronic Structure and Magnetic Properties of Cr-doped ZnO

Within the framework of Density Functional Theory (DFT) we have studied the electronic and the magnetic properties of wurtzite ZnO doped with transition-metal Cr in the presence of some defects (V o, H, V o H). The spectrum of band structure, density of states (DOS) and projected density of states (PDOS), and spin-density distribution in this system were investigated. The results of investigation shows that the existence of V o in ZnO:Cr could stabilize ferromagnetic state of the system, due to the large magnetization and density of states at Fermi level. While, the existence of H introduce donor in ZnO:Cr but just polarized above Fermi level so there is no much change observed in its magnetic properties. And as for the existence of V o H in ZnO:Cr, it turn out able to show the half-metallic properties.
