| 英文摘要 | We employ density-functional theory (dft) within the generalized-gradient approximation (gga) to investigate the formation energies, electronic structure, and magnetic properties of n impurities in zinc oxide (zno) nanowires. while the subsurface position is the preferential site for the n dopants in bare nanowires, upon hydrogen passivation n atoms segregate to surface sites. additionally we show that the defect levels in these ultra-thin wires are deeper than the ones in bulk zno, suggesting strong quantum dimensional effects. finally we investigate the possibility of ferromagnetism induced by n in zno nanowires. our spin-polarized calculations show that, although n introduces a small net magnetic moment in zno, the interaction between n dopants is weak and strongly dependent on the n position.
