Influence of Mg in electrical, optical and structural properties in Mg-doped ZnO thin film prepared by sol-gel method / Muhammad Izzat Ibrahim

This paper investigates the effect of Mg doped ZnO based on its structural, electrical and optical characteristic. ZnO were doped with MgAc with Oat%, 2at%, 4at%, 6at%, 8at%, 10at%. Spin coating method were used and samples were deposited on glass substrate. Structural characteristic of MgZnO appeared to possess the crystalline microstructures of nanometer order with uniform and dense distribution by using Field Emission Scanning Electron Microscopy(FESEM). Optical properties using Ultra Violet-Visible(UV-Vis) obtain result of spiking around 375nm wavelength, demonstrating high UV light absorption and transmittance due to incorporation of MgAc. Electrical properties were observed and obtain result of an ohmic with Platinum(Pt) metal contact for IVcharacteristics and increase linearly in term of Hall Effect measurement.
