Aerosol-assisted CVD of SnO<inf>2</inf> thin films for gas-sensor applications

In this article is a report of SnO2 deposition by aerosol-assisted (AA)CVD from tin complexes, [Sn(18-Cr-6)Cl4] and [Sn(H2O)2Cl4](18-Cr-6). The structure and properties of the precursors, used to synthesize SnO2 layers by AACVD for the first time, are characterized with the help of X-ray diffraction...

Descripción
Sumario:In this article is a report of SnO2 deposition by aerosol-assisted (AA)CVD from tin complexes, [Sn(18-Cr-6)Cl4] and [Sn(H2O)2Cl4](18-Cr-6). The structure and properties of the precursors, used to synthesize SnO2 layers by AACVD for the first time, are characterized with the help of X-ray diffraction (XRD), infrared (IR), and thermogravimetric analysis (TGA). Each complex is deposited by AACVD at 250, 400, and 500°C in a flow of N2. The resulting films are studied by XRD and atomic force microscopy (AFM). Gas-sensing properties of the deposited layers are tested to 10ppm NO2 in air. The maximum sensor response to the analyte is measured at 300°C. Copyright © 2011 WILEY-VCH Verlag GmbH & Co.
