- Аннотация: The temperature dependence of electrical conductivity and magnetoconductivity of new type of carbon films composed of nanosize thin graphite-like crystallites were investigated at temperature interval of 4.2-300 K and in the magnetic field range of 0-12 kG at 4.2 K, respectively. The crystallites consist of several (5-50) graphene layers which have predominant orientation perpendicularly to a film surface. At temperature <= 30 K the logarithmic conductivity decreases linearly with temperature. The positive magnetoconductivity of the films was observed in a magnetic field directed perpendicularly to the film surface in all intervals of field values. In magnetic field B >= 4 kG the logarithmic asymptotic of conductivity from magnetic field was observed. That is characteristic of the systems with two-dimensional quantum corrections to magnetoconductivity. In a magnetic field directed along a film surface, the crossover from negative to positive magnetoresistivity is observed at B >= 8 kG. (c) 2006 Elsevier Ltd. All rights reserved.
