Abstract

SnO₂:Sb thin films were prepared by the spray pyrolysis technique on optical micro slide glass at substrate temperature 793 (± 5) K. The relationship between the antimony doping level and the electrical, structural and optical properties of the films were investigated. The X-ray diffraction patterns showed that the films are polycrystalline. The grain size varies from 28.19 to 33.59 nm. Atomic force microscopic study revealed the surface of SnO₂:Sb to be made of nanocrystalline particles. The electrical study has revealed that the films are degenerate and exhibit n-type electrical conductivity. The SnO₂:Sb films had a minimum resistivity of 0.28 × 10^-4 W cm, maximum carrier density of 37.6 × 10¹⁹ cm^-3 and mobility of 590 cm²/V.s. The sprayed SnO₂:Sb film having minimum sheet resistance of 0.17 W/cm², highest figure of merit of 135 × 10^-4 W^-1 at 550 nm. The sheet resistance attained for the doped film in this study has been lower than the values reported for 2 wt % antimony doped tin oxide films prepared from aqueous solution of SnCl₂·2H₂O precursor. The obtained results revealed that the structures and properties of the films were greatly affected by doping levels.
