Synthesis and Characterization of TiO2 Thin Film by Self-Assembly Method

Article Preview

Abstract:

TiO2 thin films were deposited on SAM-coated silicon substrate by layer-by-layer self-assembly method. The influence of various parameters was investigated to optimize the conditions and the results show that with increasing deposition temperature and deposition time, and decreasing molar ratio of HCl to TiO22+, the content of TiO22+ in the reaction solution decreases. The as-deposited thin films were fully amorphous from the result of XRD, also were homogeneous and continuous produced at 80 °C for120 min as presented in SEM images, and the average size of particles on the thin film surface is approximately 33 nm.
