Micro structure of hydrothermal ZnO rods on micro cantilever surface

Abstract

This study reports the microstructure of Hydrothermal ZnO rods on Micro cantilever Surface. Synthesis of ZnO rods consists of two processes e.g. a formation of seed layer using Zinc asetate dihydrate by a dip-coating and a growth of the ZnO rods using Zinc-Nitrate-Tetrahydrate at temperature 95°C for time variations of 1 hours, 2 hours, 3 hours, 4 hours, 5 hours, and 6 hours. Drying condition for both seed layer and growth of ZnO rods was done at a temperature of 120°C for 2 hours. The characterization of ZnO rods morphology was done by Field Emission-Scanning Electron Microscopy (FE-SEM), chemical element composition was performed with Energy Dispersive Spectrometry (EDS), crystal structure was done by X-ray Diffraction (XRD) and functional group analysis was done by Fourier Transform Infrared (FTIR). The characterization results show that the formation of Zinc Oxide with confirmed hexagonal form of FE-SEM and XRD results. The FE-SEM results show that the variation in growth time has an effect on the diameter size formed above the microcantilever. The longer the growth time, the larger the diameter of ZnO rods.
