▎ 摘　　要

GO films exhibited dual proton and electron conduction. Proton conduction showed the exponential dependence on relative humidity with the activation energy E-a = 0.9 +/- 0.05 eV. For the electron conductivity (220-273 K) induced by thermolysis and chemical means E-a = 1.15 +/- 0.05 eV. With increasing humidity, the electron conduction went down, which was associated with recombination phenomena. The GO films can be regarded as a first example of the mixed electron-proton conduction when sample conductivity can be regulated by external influence (humidity). Field effect is detected and studied in the transistor on the basis of the GO in different types of conduction.
