Microstructural, functional group and electrical properties of nano-structured ITO-NiO layer via sol-gel process
Hazem Bouraoui, Soufiane Benhamida, Yamina Benkrima
In the present work, pure nano-crystalline nickel oxide (NiO) thin films were deposited on ITO glass substrates by employing sol-gel spin coating process. The microstructural, functional and electrical properties have been studied. The X-Ray diffraction (XRD) patterns revealed that the synthesized films are polycrystalline nature and corresponding to the cubic crystal structure with predominant orientation along (200) plane. The Fourier transform infrared spectroscopy (FTIR) analyses confirm the formation of NiO nanoparticles The electrical characterization shows that the NiO film are p-type conductivity. However, resistivity and carrier mobility of the NiO films were also measured.
