摘要:Based on the full-potential linearized augmented plane wave (FLAPW) method, the electronic structures and magnetic properties in Cu-doped CdS diluted magnetic semiconductors (DMSs) have been investigated. The results indicate that Cu-doped CdS systems show half-metallic character with a total magnetic moment of 1.0 μ_B per supercell. In the case of two Cu atoms substituting for Cd atoms, the long-range ferromagnetism is observed, which results from Cu(3d)S(3p)CdS(3p)Cu(3d) coupling chain. The estimated Curie temperature of Cu-doped CdS is predicted to be 400 K, higher than room temperature. These results suggest that Cu-doped CdS may be a promising half-metallic ferromagnetic material for practical applications in electronics and spintronics.
