Abstract:
The evolution of the electron transport character in thin films of $\mathrm{Mo}$–$\mathrm{C}$ 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 $\mathrm{Mo}$–$\mathrm{C}$ 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 $\mathrm{Mo}$ 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.
