Abstract

Thermoelectric power (TEP) of iodine monochrolide-graphite intercalation compounds (ICl–GICs) exhibits a linear temperature dependence at low temperatures, which is ascribed to the diffusion term. Above 200 K TEP levels off. This behavior stems from the phonon drag effect. By choosing an appropriate parameter set Sugihara’s theory can provide a good fit with the observed TEP results for the stage-1 and -2 ICl–GICs.
