摘要
The effect of intercalation with CuCl//2 on the temperature variation of the thermal conductivity, thermopower, and electrical resistivity of pitch-derived carbon fibers in the temperature range 2 less than T less than 300 K is studied. At high temperature, the lattice thermal conductivity is smaller than that of the pristine fibers while at low temperature an enhancement of both the lattice and the electronic thermal conductivities is observed. The thermopower is positive and exhibits a temperature dependence very similar to that generally reported in acceptor-type graphite intercalation compounds.
