Abstract: | |
Barium Oxide BaO thin films were investigation by precipitating barium chloride and analyzed structurally and optically. Samples were prepared at different thickness (75, 103, 109, and 112) nm, and glass substrate temperature kept at (450 oC) in all cases. Compressed Nitrogen was used as a carrier gas. The samples of the BaO films were characterized by X-ray diffraction (XRD), and atomic force microscopy (AFM). The XRD results indicated that the synthesized BaO thin films have a pure cubic structure. It can be seen that the highest texture coefficient was in (111) plan for thin films. AFM measurement showed the grain size ranging from (92.2-125.18) nm. The optical band gap energy (Eg) of BaO thin films from (2.4 – 2.6) eV and the (Eg) decrease with increasing thickness utilizing the optical data using UV-Vis spectrophotometer. |
