2-dimensional arrays of Co-and Pd-clusters embedded in carbon films were fabricated by means of heat-treatment method of carboxylated cellulose films after the exchange of COOH-group protons by Co-and Pd-cations. The sizes of metal clusters within range 10 nm−1 µm were obtained in dependence on the heat-treatment temperature. The dependencies of the resistance on temperature and magnetic field for the samples annealed at T = 700• C and 900• C were measured. The R(T ) dependencies both for carbon films with Co-and Pd-clusters can be fitted by expression R = R0 exp(T0/T ) 1/n inherent for variable-range hopping. In the whole range of investigated magnetic field and temperature magnetoresistance was negative and can be related to quantum interference in the variable range hopping transport along neighboring alternative paths.

“…This VRH model has been applied in various branches of condensed matter physics. In recent years, the VRH model has been invoked in metal insulator transition [5], insulating amorphous alloys [6], thin film transistors [7], inorganic compounds [8] and in mesoscopic carbon networks [9]. A variant of the VRH model known as the quasi-one-dimensional VRH model [10] has been applied to charge transport in the disordered regime of HCl-doped PAN-ES samples.…”
