Abstract

The aim of this study is to synthesis the aluminium doped zinc oxide thin film prepared using chemical bath deposition. The raw materials used were zinc nitrate powder, aluminum nitrate powder and ammonia solution. The aluminium nitrate ratio is the key parameter to improve the electrical conductivity in the zinc oxide thin films. The parameters used for aluminium nitrate percentage are 0.00, 0.02, 0.04, 0.06, 0.08, and 0.10. Then, the processes involved during synthesis of zinc oxide thin films were solution mixing, heated solution and heat treated in 400°C for 2 hours. The thickness measurement used a weight difference method where the weight and thickness of substrate will be taken before and after deposition. A scanning electron microscope (SEM) was employed to characterize the morphology of the zinc oxide thin films to obtain the high resolution image with magnification of 5 to 1,000,000x and an X-ray diffraction was engaged to observe the crystallography of ZnO thin films.
