Structural and Optical Properties of Polycrystalline NiO Thin Films Prepared by Using the Oxidation of the Metallic Ni

다국어 초록 (Multilingual Abstract)

Here, we report on the structural and the optical properties of polycrystalline NiO thin filmsprepared by using the thermal oxidation of metallic Ni. After the deposition of the Ni films, theywere placed in a thermal oxidation furnace at different temperatures (400, 500, 600, 700, and 1000C), resulting in mean crystallite sizes between 6 nm and 40 nm. From the optical absorptionspectra, we determined the energy gaps of these films. Interestingly, the energy gaps were in therange of 3.13 3.29 eV, which were smaller than those of the bulk.
