Conductive Properties

Al and Sb codoped ZnO thin films were prepared through a sol-gel spin coating method on glass substrates and annealed in different atmospheres. The XRD results show that the films have hexagonal wurtzite ZnO structure and SEM results reveal that the films annealed in hydrogen consist of hexagonal nanorods with diameters of 84 nm and lengths of 422 nm, however the films annealed in other atmospheres without nanorods. The photoluminescence (PL) spectrum shows that the emission peaks of the films are mostly at 390 and 460 nm, and the film annealed in hydrogen has the strongest intensity of peak at 390 nm and the film annealed in air has the strongest intensity of peak at 460 nm. The electrical properties show that the films annealed in hydrogen have a lowest resistivity of 1.02×10-3 Ω•cm.

Ito Thin Films

In this paper, the indium tin oxide (ITO) thin films were prepared by a sol-gel spin coating method and then annealed under different temperatures (400, 500 and 550°C) in a mixture atmosphere of 3.75% H2 with 96.25% N2 gases. The microstructure, optical and electrical properties of the prepared films were investigated and discussed. The XRD patterns of the ITO thin films indicated the main peak of the (222) plane and showed a high degree of crystallinity with an increase of the annealing temperature. In addition, due to the pores existing in the prepared films, the optical and electrical properties of the prepared films are degraded through the sol-gel process. Thus, the best transmittance of 70.0 %in the visible wavelength region and the lowest resistivity of about 1.1×10-2 Ω-cm were obtained when the prepared film was annealed at 550°C.
