Abstract

Efros–Shklovskii variable range hopping (ES-VRH) conduction mechanism $[\rho = \rho_0 exp(T_{ES}/T )^{1/2}]$ is observed in composites of polymer and iron carbide nanoparticles embedded in carbon relatively at high temperatures. A crossover from one ES-VRH type to another ES-VRH type is observed with different ES temperature $(T_{ES})$ and prefactor (\rho0) as temperature decreases.
