Growth Of Fluorine Doped Zinc Oxide Nanostructures For Ultra-Violet Photodetector Using Modified Chemical Bath-Hydrothermal Method

The main aim of this research work was the use of modified chemical bath- hydrothermal method for the synthesis of undoped and fluorine doped zinc oxide (FZnO) for ultra-violet (UV) photodetector (PD) application. The effect of fluorine (F) concentration in ZnO properties was investigated on Si subs...
