Structural, optical, morphological and electrical properties of indium oxide thin films prepared by sol gel spin coating process

Aluminium (Al) doped zinc oxide (ZnO) has been considered as one of the promising transparent conducting oxide for wide applications in electronic devices. In this investigation, sol-gel spin coating process were employed to fabricate Al:ZnO on glass coated with indium tin oxide (ITO) substrate. In order to expose the effects of aluminium concentration on the structural and electrical properties of the ZnO films, different Al concentrations (1 at.%, 3 at.% and 5 at.%) were used. A field emission scanning electron microscope (FESEM) and a two point probe were employed to examined the material properties of the Al:ZnO films. Through the FESEM results, the Al:ZnO films show different morphologies behaviour with increasing the Al concentrations. Besides, the electrical conductivity was increased by increasing the dopant source and the lowest resistivity was obtained at 5 at.%. In general, the Al concentration exerts strong influence on the ZnO films properties. Keywords: Transparent conducting oxide, X-ray diffraction, sol gel

AbstractNeodymium niobate NdNbO4 (NNO) and tantalate NdTaO4 (NTO) thin films (~100 nm) were prepared by sol-gel/spin-coating process on Pb(Zr0.52Ti0.48)O3/Al2O3 substrates with annealing at 1000°C. The precursors of films were synthesized using Nb or Ta tartrate complexes. The XRD results of NNO and NTO films confirmed tetragonal T-NdNbO4 and T-NdTaO4 phases, respectively, with traces of monoclinic MNdNbO4 and M´-NdTaO4. The surface morphology and topography were investigated by SEM and AFM analysis. NTO was smoother with roughness 5.24 nm in comparison with NNO (6.95 nm). In the microstructure of NNO, small spherical (~ 20-50 nm) T-NdNbO4 and larger needle-like particles (~100 nm) of M-NdNbO4 phase were observed. The compact clusters composed of fine spherical T-NdTaO4 particles (~ 50 nm) and cuboidal M´-NdTaO4 particles (~ 100 nm) were found in NTO. The results of this work can contribute to formation of different polymorphs of films for the application in environmental electrolytic thin film devices.
