The proton conductivity of graphene oxide (GO) and Nafion films was studied depending on the humidity and voltage on electrodes. The electric properties of the films were similar, but the mobility of positive charges in Nafion was approximately two o

Proton conductivity in graphene oxide and Nafion films depending on humidity and voltages across electrodes is studied in the model of a field-effect transistor. The electrical characteristics of the films are similar to one another, but the mobility

The dark process (posteffect) of increasing the electrical conductivity and spectral absorption in the graphene oxide (GO) film after its preliminary UV irradiation has been studied. The posteffect is due to the conformational relaxation of the struc

The O/C atomic ratios in films of oxidized and partially reduced graphene oxide are determined via the Rutherford backscattering of H+ ions. In addition, the conductivity σ is measured. It is established that the reduction noticeably decreases the

Under the action of ionizing radiation on a PVDF film, fluorine and hydrogen atoms bound to its linear carbon chain with single chemical bonds detach. Free atoms and HF molecules diffuse toward the film surface and escape from it. As a result of irra

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 c

Electron mobility in a thin silicon layer of a metal-insulator-semiconductor-insulator-metal system is studied as a function of longitudinal and transverse electric fields (in wide ranges of their values), temperature in the range 1.7 to 400 K, and c
