Owing to the low doping concentration of nitrogen and strong compensation of intrinsic donors, the attainment of highly conductive
p-type ZnO films remains one of the largest challenges for the application of ZnO. An approach has been proposed to increase
the doping concentration of nitrogen in ZnO by exposing the ZnO:N films in the ambient of nitrogen plasma periodically in
this paper. Hall measurements and photoluminescence spectroscopy indicate that this approach is effective in improving the
hole concentration in ZnO films. Under the optimized conditions, a p-type ZnO film with a hole concentration of 1.68 × 1018 cm−3 has been achieved. 相似文献

N-doped ZnO thin films have been grown on sapphire substrates by dielectric barrier discharged pulsed laser deposition (DBD-PLD). Low temperature photoluminescence spectra of N-doped ZnO film verified the p-type doping status to find the acceptor-bound exciton peaks with the high resolution detection. At low temperature growth, the major defects in the N-doped ZnO film were the oxygen interstitials that can combine with N, so that the N played the role as an acceptor. On the other hand, the major defects in the samples processed at high temperature were oxygen vacancies with which N doesn't play the role as an acceptor. The acceptor binding energy of N acceptor was estimated to be about 105 meV. 相似文献

Recent efforts on doping ZnO films for charge and spin functionality are reviewed, focusing on chemical doping for charge and spin device formation. Discussion includes the behavior of phosphorus as an acceptor and magnetism in transition metal-doped ZnO. Evidence for p-type behavior in phosphorus-doped (Zn,Mg)O grown by pulsed laser deposition is presented. The magnetic properties of ZnO co-doped with Mn and Sn are also discussed. 相似文献
