摘要：

The frequency (10-108 Hz) and temperature (100-400 K) dependence of the ac conductivity of anthracene carbons is explained within two theoretical models. The properties of carbon heat treated up to 600°C are correctly explained by means of a model where the current flow is due to electron hops over a potential barrier between localized sites. The conductivity of the carbon heat-treated up to 650°C is interpreted using a theory proposed by Mott and Davis. The spatial densities of states are determined in both cases. © 1979.
