TEMPERATURE-DEPENDENCE OF ELECTRICAL-RESISTIVITY IN TERNARY GRAPHITE-INTERCALATION COMPOUNDS

The in-plane electrical resistivity of non-exfoliated stage 2 and stag e 5 K-FeCl3 graphite intercalated compounds was measured at a wide ran ge of temperatures by using the standard four probe technique. The dat a of stage 5 exhibited a conductive behavior which is in contrast to t he same stage of an exfoliated sample. The electrical resistivity exhi bits a metallic behavior similar to the same stages of binary compound . The data are well fitted by a quadratic T -dependence.
