Abstract
The production of TiO2 nanostructured thin film was synthesized by sol-gel method using TiO2 nanopowder as precursor. The solution of TiO2 was then deposited as thin film onto glass substrate by spin-coating technique. The aim is to investigate the effect of concentrations on the surface morphology and electrical properties of the thin films. The effect on the surface morphology was observed by Field Emission Scanning Electron Microscopy (FESEM) and Atomic Force Microscopy (AFM). The electrical properties were then observed by two-point probe method. By measuring the current-voltage (IV) characteristic, resistivity and conductivity can be measured. The purpose of this paper is to investigate the surface morphology and the IV characteristic of the thin films.
