CONSTRUCTING A ZnO NUCLEI CRYSTAL SEMICONDUCTOR LAYER ONTO ITO GLASS WITH A CUSTOM-MADE SPIN-COATING EQUIPMENT

Abstract

A custom-made spin coating equipment was designed and fabricated to apply in synthesizing the homogeneous thin films of nuclei materials with low cost and easy to use. The asfabricated equipment can work at the rate of from 300 to 4800 rpm. The equipment was built on Arduino technique and 3D printing technology. On the other hand, thin film of ZnO crystalline nuclei material was synthesized on an ITO glass with diameter 25 mm x 25 mm by using the asfabricated spin coater and annealing method. Modern physicochemical analytical techniques used
to characterize the thin film material such as X-ray diffraction (XRD), scanning electron
microscopy (SEM) resulting in the crystal structure and morphology of the film. The nuclei film
of material is crucial stage of growing the material on a planar base
