Preparation of zink oxide nanorods on thin film template using Sol-Gel method for humidity sensor application / Chempaka Mohd Din

This paper focuses on the preparation of Zinc Oxide (ZnO) nanorods on thin film template for humidity sensor that has been prepared by Sol-gel method. Spin coating process is used to deposit thin film of 5, 10, 15 and 20 layers which act as catalyst foliowed by immersion process for growth of nanost...
