Effect of co-doping process on topography, optical and electrical properties of ZnO nanostructured
We investigated of Undoped ZnO and Magnesium (Mg)-Aluminium (Al) co-doped Zinc Oxide (MAZO) nanostructured films were prepared by sol gel spin coating technique. The surface topography was analyzed using Atomic Force Microscopy (AFM). Based on the AFM results, Root Mean Square (RMS) of MAZO films...

| Summary: | We investigated of Undoped ZnO and Magnesium (Mg)-Aluminium (Al) co-doped Zinc Oxide (MAZO)
nanostructured films were prepared by sol gel spin coating technique. The surface topography was analyzed using
Atomic Force Microscopy (AFM). Based on the AFM results, Root Mean Square (RMS) of MAZO films have rougher
surface compared to pure ZnO films. The optical and electrical properties of thin film samples were characterized using
Uv-Vis spectroscopy and two point probes, current-voltage (I-V) measurements. The transmittance spectra for both thin
samples was above 80% in the visible wavelength. The MAZO film shows the highest conductivity compared to pure
ZnO films. This result indicates that the improvement of carrier mobility throughout doping process and possibly
contribute by extra ion charge. |
