| Abstract: | In some liquid chalcogenide systems, the activation energy derived from thermopower is larger than that derived from the temperature dependence of conductivity. This anomaly is accounted for with an asymmetric density of states model in which an electronic contribution to thermopower increases exponentially with temperature. |
