Microscopic Properties of Graphite Intercalation Compounds

摘要: In this chapter we review the subject of microstructural properties in graphite intercalation compounds (GICs). GICs, obtained by intercalating various atomic or molecular species into van der Waals galleries between host crystalline layers, are not expected to exist with perfect single-crystalline structures. Microstructure GICs is generally unavoidable for following reasons: (1) finite lateral extent intercalant layers associated staging phenomenon, (2) multiphase nature in-plane structures due quenching from elevated temperature (even if thermal equilibrium has been reached at temperature) observation temperature, and (3) inherent defects crystals resulting “incomplete” annealing. Other factors, such as disproportionation, stoichiometric variation, incomplete intercalation, partial desorption, further complicate microstructure.
