Preparation and characterization of TiO2/carbon nanowall composite on a transparent substrate

Mattia Pierpaoli, Aneta Lewkowicz, Mateusz Ficek, Maria Letizia Ruello, Robert Bogdanowicz


A transparent titanium dioxide and carbon nanowall composite (B-CNW/TiO2) material was fabricated by growing boron-doped carbon nanowalls (B-CNWs) on quartz glass with microwave plasma-enhanced chemical vapor deposition technique, followed by sol-gel deposition using titanium isopropoxide as a TiO2 precursor. Different layer thicknesses were fabricated. Samples were investigated by spectroscopic ellipsometry and UV-VIS spectroscopy. Results shows how the B-CNW thickness affects the optical transmittance, bandgap and electrical conductivity.
