Microsphere templating as means of enhancing the sensitivity of thin film metal-oxide gas sensors
Chemical and physical synthesis routes were combined to prepare macroporous thin films of semiconducting metal-oxides such as SnO2, TiO2, ZnO, and CaCu3Ti4O12 by reactive sputtering or pulsed laser deposition onto polymethylmethacrylate and polystyrene microsphere templated [...]
