Nanostructured SnO2 Films: Room Temperature NH3 Sensing
Gas sensing characteristics of the tin oxide SnO2 thin films towards ammonia (NH3) were investigated. This sensor exhibits good response and recovery at room temperature. In addition, SnO2 films were investigated for its structural, morphological, electrical and optical properties. The proposed sensor shows different electrical response in the detection of the vapors like methanol, ethanol, formaldehyde, and Trimethylamine (TMA). Among many other vapors, SnO2 showed better sensing response towards NH3.
