| Abstract: | Thin films of LixMoyOz have been deposited on glass substrate in a one step chemical vapour deposition using a single source solid precursor. The
films were characterized using Rutherford Backscattering Spectroscopy (RBS), X-Ray Diffractometry, Scanning Electron Microscopy
(SEM), Impedance Spectroscopy (IS), van der Pauw conductivity measurement and Ultraviolet-Visible Spectroscopy. Results of
the characterization showed that the films are dendritic, polycrystalline and semiconducting with an optical transition energy
of 3.0 eV. IS characterization gave a semicircle in the complex impedance plot. The conductivity vs. temperature plot showed
a transition at 450 °C and also a hysteresis. Analysis showed the film to be mixture of phases. |
