Abstract
The conductivity and thermopower data seem to be explained in their general features by the two-dimensional variable-range hopping model. The most compelling evidence is provided by the extremely good linearity of the log σT 3/2 plots versus T−113 over the measured temperature range (100–450 K), with very reasonable values of the parameters involved in this model. The two-dimensional system is identified with the large planar macromolecules which can be thought of as forming a structure of randomly packed flat ribbons.Keywords
