Abstract

The room temperature sensing of ozone by transparent p-type semiconductor CuAlO₂ was discussed. A transparent p-type semiconductor, CUAlO ₂, shows selective and reversible response to ozone gas at room temperature. This materials potential could be exploited using a combination of the p-type transparent CuAlO₂ with an existing n-type ozone sensing material In₂O₃ to fabricate hybrid ozone sensing devices and environmental optoelectronic devices. It was observed that transparent p-type semiconductor, CuAlO₂ has an optical band gap of 3.5 eV.
