Transparent conducting Nb-doped titanium oxide (NTO) films were deposited on a non-alkali glass substrate using an RF magnetron sputtering method with post-annealing. Structural, electrical and optical properties of the NTO films were found to be strongly dependent on film thickness. A resistivity of 4.2 × 10−3 Ω cm and an average visible transmittance of ∼70% were obtained at the film thickness of 360 nm, indicating that the polycrystalline NTO fabricated by the sputtering method has sufficient potential as a transparent conducting oxide (TCO) candidate for practical applications.
