Abstract
Spray pyrolysis and microwave plasma chemical vapor deposition techniq ues have been employed successfully for the deposition of CuO impregna ted SnO2 films suitable for sensing hydrogen sulfide and methyl mercap tan. The observed change in conductivity of these films upon exposure to H2S gas in air has been explained on the basis of the band theory o f solids.
