Abstract
The interaction of SnO2(CuO) polycrystalline films with H2S+N-2 gas mi xtures has been investigated by conductivity measurements, Auger elect ron spectroscopy, secondary neutral mass spectrometry and X-ray diffra ction. A significant effect of film conductivity increase in the prese nce of H2S has been found. It is suggested that the reversibility of t he electrical properties of the doped films may be produced by a chang e in the copper state in the tin dioxide by means of selective chemica l reactions with H2S and oxygen accordingly.
