Synthesis and characterization of ZnO/ZnAl2O4/ Zn2TiO4 composite films by AreO2 mixture hollow cathode glow discharge

In this study, ZnO/ZnAl2O4/Zn2TiO4 composite nanostructured thin films are deposited assisted with hollow-cathode glow discharge (HCD). The films are deposited using various argon-oxygen gases mixture (0e50% O2), and its effect on film quality, optical and electrical properties is examined. Remarkab...
