Ferromagnetism in p-Type Manganese-Doped Zinc Oxide Quantum Dots

The magnetic exchange interactions between paramagnetic Mn2+ dopants in the presence of a N2– p-type defect in zinc oxide quantum dots are studied using density functional theory. Spin-dependent delocalization of the N2– 2p acceptor level among the nearest-neighbor Mn2+ dopants is observed. The calc...
