Abstract : The influence of a SO2 treatment on the electrical properties of SnO2 has been studied. It is shown that some gaseous compounds induce an important maximum on the curve of the electrical conductance as a function of the temperature of SnO2 treated with SO2. The temperature at the maximum conductance is connected with the nature of the electrical contacts (gold or platinum) and an important part is associated with the metal-oxide interface process. The selective aspect of the electrical response can be exploited to develop a benzene detector.
