Sol-gel deposition and electrical properties of laser irradiated Cu doped TiO2 multilayer thin films
Multilayer thin films (3, 5 and 7) of 20% copper doped titanium dioxide (Cu:TiO2) have been deposited on glass substrates by sol-gel spin coating method. After deposition, films have been irradiated by a beam of continuous wave diode laser (532 nm) for two minutes at the angle of 45°. Structural, su...
