Abstract |
ZnO/Ag/SnO2 (ZAS) tri-layer films were prepared on glass substrates via RF and DC magnetron sputtering, and then the influence of the thickness of the ZnO and SnO2 layers on the optical and electrical properties of the ZAS films was investigated. As deposited ZnO 50 nm/Ag 10 nm/SnO2 50 nm films showed a higher figure of merit, 1.08 × 10-2 Ω-1, than the other films due to a high visible transmittance of 80.8% and a low resistivity of 1.21 × 10-4 Ωcm. From the observed results, it can be concluded that the ZnO 50 nm/Ag 10 nm/SnO2 50 nm tri-layer films can be used as a substitute for conventional transparent conducting oxide films in various opto-electrical applications.
