Preparation of titanium dioxide via sol gel method: effect of molarity concentration / Hanis Sutan Abd Latif Hamidi

In this project, Ti02 thin film was deposited by using sol gel deposition process. The TiC>2 thin film prepared by sol gel method and utilizing titanium tetra (IV) isopropoxide, (TTiP) as precursor. This paper is focused on the effect of varying the precursor to the electrical properties, optical...
