| Summary: | This paper focuses on the effect of humidity on electrical properties of nanostructured Zinc Oxide thin film prepared by using sol-gel method by changing the concentrations of the solution. Molarities of 0.002, 0.004 and 0.006 mol of Zinc Acetate solution was observed. The surfaces and electrical properties of the ZnO were characterized using Scanning Electron Microscopy (SEM), and I-V measurement respectively. Results from SEMs indicate that ZnO nanorods are formed with average size between 364nm to 75nm witli different molarities. Results from the I-V measurements indicate that 0.004M concentration is the suitable solution for humidity sensor applications since the ability of the ZnO nanorods to adsorb of the moisture molecules by the nanostuctured ZnO at the surface of the samples. |
