Abstract:

Microstructure, optical and electrical properties of ZnO-doped (Zr0.8Sn0.2)TiO4 thin films prepared by rf magnetron sputtering on ITO/Glass substrates at different argon-oxygen (Ar/O2) mixture have been investigated. The surface structural and morphological characteristics analyzed by X-ray diffraction (XRD) and atomic force microscope (AFM) were found to be sensitive to the Ar/O2 ratio. Optical transmittance spectroscopy further revealed high transparency (over 70%) in the visible region of the spectrum. At an Ar/O2 ratio of 100/0 and a substrate temperature of 400°C, the ZnO-doped (Zr0.8Sn0.2)TiO2 films possess a dielectric constant of 44 at 10 MHz, a dissipation factor of 0.03 at 10 MHz, a leakage current density of 3.73×10-9 A/cm2.
