Abstract—The temperature dependence of the electric conductivity 
(T) of carbon monofilament fibers was
measured over a temperature range of 10 to 300 K. The fibers were prepared from hydrated cellulose by thermal
treatment at 800, 1000, 1200, 1500, 1800, 2200, and 2400
C. The results obtained were interpreted within the
framework of a model of heterogeneous electric conductivity that takes into account several charge-transport
mechanisms simultaneously operative in the homogeneous (on the average) carbon fiber material. The contri-
butions of these mechanisms to the conductivity were identified and evaluated based on the experimental data
obtained.
