Abstract
The c-axis thermal expansion of several alkali-graphite intercalation compounds has been measured by means of x-ray scattering between 15 and 300 K. The thermal expansion depends strongly on the stage of the compound and is largest for C8M (M=K, Rb, Cs) compounds. The data have been analyzed in terms of an one-dimensional quasi-harmonic approximation, which yields Grüneisen parameters two or three times as large as for pristine graphite.
