ABSTRACT
Al-doped Zn1-xMgxO films have been deposited on glass substrates at a substrate temperature of 200 °C by a pulsed laser deposition system. A resistivity of 3×10-4 Ω cm was obtained at x=0.06. Film resistivity was found to increase with further increases in Mg composition. The maximum band gap of films with a resistivity ρ≤1×10-3 Ω cm was found to be 3.97 eV, demonstrating band-gap engineering possibilities in the range of Eg=3.5–3.97 eV with a resistivity ρ≤1×10-3 Ω cm. The average transmittance of the films was higher than 90% in the wavelength region λ=400–800 nm, a range suitable for transparent conducting film applications.

    Pulsed laser deposition (PLD) is a good method for growing high-quality functional oxide thin films because of the technical simplicity and the ease with which deposition can be switched from one material to another. However, the repeatability of film quality is often hard to achieve, especially...
