Abstract

Thin films of titanium dioxide are deposited on gas-sensor substrates at 450 °C from the aerosol-assisted (AA)CVD of titanium isopropoxide solutions in toluene under the influence of electric fields. Electric fields are generated by applying a potential difference between the inter-digitated electro...
