摘要
A new p-type dilute magnetic semiconductor was synthesized on the basis of manganese-doped ZnSiAs2 chalcopyrite. As the manganese percentage in ZnSiAs2 increased, the Curie temperature increased from 325 to 337 K for compositions containing 1 and 2 wt % manganese. The ferromagnetic properties of the new dilute magnetic semiconductor were due to nanoclusters that were generated by concurrent substitution of manganese for elements in the cationic sublattice of chalcopyrite.
