| الملخص: | The work highlights the research on the electrical properties and the surface morphology of the nanostructured Zinc Oxide (ZnO) thin film for humidity sensor. The electrical v/l properties is depends on the Current-Voltage (I-V) measurement while the surface morphology is characterized by using Scanning Microscopy (SEM). The thin film were deposited on the glass substrate using spin coating technique while the nanostructured ZnO were prepared using Sol-gel method. The solutions for nanostructured ZnO are varies by using different starting material such as Zinc Acetate, Zinc Nitrate, Zinc Acetate doped with Aluminium and Zinc Nitrate doped with Aluminium based on the same molarities of 0.004M concentration. The surface morphology indicates that the size of nanostructured ZnO is increasing when doping with 1% of Aluminium. The I-V measurements result shows that, the sample Zinc Acetate doped with Aluminium is the suitable materia! for the humidity sensor since the sensitivity is higher than other samples |
