Abstract

Na-N co-doped p-type ZnO ∶ (Na

N)] thin films were prepared on glass substrates by RF reactive magnetron sputtering and post-annealing techniques in the N

O ambient. X-ray diffraction (XRD) measurements showed that all films possessed a good crystallinity with

-axis preferential orientation. After annealing

the intensity of the (002) diffraction peak and the value of 2

increase and the FWHM decreases. Hall measurements showed that the electrical properties of ZnO ∶ (Na

N) films were improved after annealing and the p-type behavior was realized. The film annealed at 450 ℃ showed the lowest resistivity of 139.2 Ω·cm with a Hall mobility of 0.2 cm

. XPS measurements showed that Na

acceptor in ZnO ∶ (Na

N) is responsible for the p-type conductivity of the ZnO ∶ (Na

N). In addition

Na-N complex may exist in the films

which acts as acceptor. Detailed investigation is now in progress.
