Abstract

The effect of chemical etching of the glass substrate with sulfuric acid on the thermal stability of the titanium oxide thin film prepared by metal organic chemical vapor deposition (MOCVD) at the temperature range of 300-350 °C is investigated. The thickness and stoichiometry of the films were studied by Rutherford backscattering spectrometry (RBS) and the thermal stability of the films were examined with x-ray photoelectron spectroscopy (XPS). Boiling the glass in sulfuric acid was found to be an effective method to extract the sodium and calcium in the glass, and was found to suppress the out-diffusion of sodium and calcium in the titanium oxide.
