  • Abstract
    Gas sensing characteristics of tin oxide thin films prepared using rheotaxial growth and thermal oxidation (RGTO) have been investigated as a function of temperature and concentration. These films are found to show maximum response towards H2S at a temperature of 250°C. Sensor response is observed to follow a power law S = A[C]0.7 in concentration range of 1-100 ppm. The response of these films was also tested for other toxic gases and these films were found to show selectivity towards H2S.
