摘要：

Effect of 1 MeV electron irradiation with the dose up to 160 x 10(15) cm(2) on the electrical properties of reduced graphene oxide paper (rGOP) was investigated in a temperature range of 8-300 K. It was found that rGOP has fairly high irradiation stability, but sufficiently high dose causes nonmonotonic changes in the resistivity. The effect of electron irradiation on the resistivity is more substantial under the low temperatures of electrical measurements. It was assumed that the modification of electrical properties is due to the effect of electron irradiation on the ensembles of the sp(3)-hybridized carbon atoms. It was shown that in the studied rGOP, the transport of charge carriers occurs by variable range hopping conductivity in the wide temperature range and conduction mechanism remains the same after electron irradiation.
