We investigate charge transport properties of reduced graphene oxide (RGO) and RGO based composite materials (RGO-ZnSe, RGO-ZnTe) in 84K-473K temperature range. Resistance curve derivative analysis (RCDA) shows that Mott two dimensional variable range hopping (2D-VRH) is the dominant charge transport mechanism for RGO whereas RGO based composites show Mott 3D-VRH in 84K- 280K temperature range. At higher temperatures (290K-473K), the charge transport process reveals activated Arrhenius like behavior for both RGO and RGO composites. The composite materials show paramagnetic behavior despite the diamagnetic nature of individual counterparts, confirmed by electron paramagnetic resonance (EPR) SQUID magnetization measurement.
