The evolution of the electron transport character in thin films of Mo–C nanocomposites is studied over the metal concentration range 0.14 – 0.3 at temperatures from 4.2 to 400 K. It is shown that conductivity of the Mo–C nanocomposites demonstrates the distinct power-like behavior in the two temperature intervals separated at 20 – 25 K. The concentration dependences of the power exponent in both temperature intervals are characterized by the expressed minimum at Mo content close to 0.2 varying over the range 0.25 – 1.0. The experimental data are discussed and simulated in the model of inelastic tunneling of the electrons in amorphous dielectrics in the framework of the effective medium approximation.
