چکیده مقاله:

Cadmium oxide (CdO) thin films were deposited on the glass substrate by the modified SILAR method, using cadmium acetate dihydrate and ammonium hydroxide aqueous solution as precursors. The structural, surface morphological, elemental composition and optical properties of the deposited films were investigated via X-Ray Diffraction (XRD), scanning electron microscopy, EDAX, optical absorption, photo luminescence, and FT-IR spectroscopy. The XRD analysis reveals that the films were polycrystalline with cubic structure. Both crystallinity and grain size were found to increase with increasing solution concentration. The energy-dispersive spectroscopic analysis confirmed the presence of Cd and O elements. The films exhibited a maximum transmittance (50% - 70%) in the infra-red region. Transmittance was found to increase with increasing precursor concentration and estimated band gap energy (Eg) was in the range of 2.17 – 2.21 eV.

Investigation of resistive switching in anodized titanium dioxide thin films

In this work, TiO2 nanostructures were grown on titanium thin films by electrochemical anodizing method. The bipolar resistive switching effect has been observed in Pt/TiO2/Ti device. Resistive switching characteristics indicated the TiO2 nanotubes are one of the potential materials for nonvolatile memory applications.  Increasing anodizing duration will increase nanotube lengths which itself c...

Morphological Tailoring of Thin Films Prepared by Low Cost SILAR Method

The growth of highly textured Zinc oxide (ZnO) thin films with a preferred (101) orientation has been prepared by employing Successive ionic layer growth by Adsorption Reaction (SILAR) using a sodium zincate bath on glass substrates has been reported. Morphology of the films were found to be varying well from stacked nanorods to shoots of nanotubes and clustered spherical and hilly morphology w...

Dopant ion size and electronic structure effects on transparent conducting oxides. Sc-doped CdO thin films grown by MOCVD.

A series of Sc-doped CdO (CSO) thin films have been grown on both amorphous glass and single-crystal MgO(100) substrates at 400 degrees C by MOCVD. Both the experimental data and theoretical calculations indicate that Sc3+ doping shrinks the CdO lattice parameters due to its relatively small six-coordinate ionic radius, 0.89 angstroms, vs 1.09 angstroms for Cd2+. Conductivities as high as 18100...

Effect of Post Annealing on Antibacterial Activity of Zno thin Films Prepared by Modified Silar Technique

Zinc oxide (ZnO) thin films were prepared by modified Successive Ionic Layer Adsorption and Reaction (SILAR) method. The optical, structural and antibacterial properties of the prepared ZnO films were analyzed as a function of its annealing temperature lying in the range of 250oC to 450oC. Optical properties were studied using UV-Visible spectroscopy and Photoluminescence spectroscopy (PLS). Op...
