Investigation into the Gas Sensitivity in Nanostructured Films Based on Tin Dioxide by Impedance Spectroscopy

摘要

It is demonstrated that,in principle,it is possible to prepare polycrystalline films of the composition 0.9SnO_2 centre dot 0.1 CuO with one-dimensional nanoparticles on the surface and to fabricate highly sensitive gas sensors on their base.The films thus prepared are characterized by a high sensitivity to gases,to strongly polar molecules of water and ethanol,and also to oxygen.
