  • Abstract
    The behaviour of ClAlPc thin film gas sensors is studied in the presence of NO2 and O2. The change in the dark conductivity of ClAlPc thin films on exposure to NO2 at several different temperatures is investigated. In particular, the temperature of maximum sensitivity (Tmax) and the minimum temperature for good reversibility (Tmin) of ClAlPc thin films has been determined and related to gas sensor applications. Sensitivity (s) of ClAlPc to NO2 is also measured at several different temperatures. It is found that by increasing temperature the sensitivity decreases, but reversibility is greatly enhanced
