Properties of nano-structured zinc oxide thin films for ultraviolet photoconductive sensor applications / Mohamad Hafiz Mamat

Nanostructured zinc oxide (ZnO) materials in thin film structure have been synthesized using the sol-gel method. The thin film depositions have been carried out by spin-coating technique and hydrothermal aqueous chemical growth method on silicon and glass substrates. The thin films were annealed for...
