Abstract :
The interaction of SnO2(CuO) polycrystalline films with H2S + N2 gas mixtures has been investigated by conductivity measurements, Auger electron spectroscopy, secondary neutral mass spectrometry and X-ray diffraction, A significant effect of film conductivity increase in the presence of H2S has been found. It is suggested that the reversibility of the electrical properties of the doped films may be produced by a change in the copper state in the tin dioxide by means of selective chemical reactions with H2S and oxygen accordingly.
