Abstract

In this work, ZnO films were fabricated by sol-gel spin coating technique. Different spinning speeds of 1000 to 6000 revolutions per minute (RPM) were used in order to study the changes on the properties of the ZnO films. The characterizations were conducted using surface profilometer for thickness measurement, atomic force microscopy (AFM) for surface scanning, X-ray diffractometer (XRD) for structural analysis, and ultraviolet-visible (UV-VIS) spectrophotometer for optical transmittance. The influence of spinning speed and the mechanisms which affect the growth of the ZnO films will be revealed.
