• GZO films were deposited on EPN substrates using RF magnetron sputtering.
• The covalent bond length of the films decreased as the deposition power increased.
• A minimum resistivity of 2.994 × 10−3 Ω-cm was obtained as deposited at 125 W.
• GZO film with mobility and concentration of 8.652 cm2 V s−1 and 6.3417 × 1019 cm−3.
Gallium-doped zinc oxide (GZO) thin films were deposited on flexible polyethylene naphthalate substrates using radio frequency (RF) magnetron sputtering. The resulting GZO thin films were polycrystalline, displaying a hexagonal wurtzite-type crystal structure with a preferred grain orientation in the (002) direction. The covalent bond length of the films decreased as the RF deposition power increased, an inverse trend to that of the residual stress. In the transmission spectra, the absorption edge was about 380 nm, and the optical transmittance decreased from 93.2% to 88.6% in the visible range as the RF deposition power increased from 75 to 150 W. A minimum resistivity of 2.994 × 10−3 Ω-cm was obtained for the film deposited at 125 W, with a Hall mobility of 8.652 cm2 V s−1 and a carrier concentration of 6.3417 × 1019 cm−3. The figure of merit results indicated that the film deposited at 125 W possessed satisfactory optical and electrical properties for potential applications.
