摘要：
Tellurium thin films have been investigated for use as hydrogen sulphide gas sensors. The films were prepared by thermal evaporation on alumina substrates at a temperature of 373 K and were found to be sensitive towards 0.1 ppm of H2S at room temperature. The response was reproducible and the films were stable for operation over 3 months. Detection mechanism of the sensors was investigated and it was found that hydrogen sulphide reduced the amount of adsorbed oxygen on the Te film surface leading to increase in resistance.
