The purpose of this work is to study the electric properties of graphite and the synthesis of a few layers graphite intercalation compounds (GIC). First, intercalation of Li between graphite layers was done by soaking the substrates into a 20 ml n-butyllithium solution. Second, intercalation of FeCl3 into the graphite was done by heating FeCl3 powder and graphite in the quartz tube. For Li intercalation, the appearance of an extra Bragg reflection at 23.7º indicates that Li atoms were intercalated between the graphene sheets in the specimen we grew. For FeCl3 intercalation, the (00l) Bragg reflection was caused by the FeCl3-GIC. Probably Iron Chloride was intercalated in graphite. In the Raman spectra of graphite and FeCl3-GIC, the G, D and 2D peaks were confirmed. Additional peaks only in the specimen of FeCl3-GIC were observed at 1605 cm-1 and 3415 cm-1. It is speculated that the peak is related to the intercalation of FeCl3 into the graphite.
