Low Temperature Structure and Properties of Graphite Lamellar Compounds.
Abstract
The main initial objective of this E.R.O. supported research was a better understanding of the relationships between the structure and certain electronic properties of graphite intercalation compounds (GIC's) which might lead to the synthesis of compounds with a high electrical conductivity. In order to achieve this, three kinds of research were developed 1) Much time was devoted to preparing samples of pure compounds, without macroscopic defects such as cleavages or curvatures, and with a mosaic spread as low as possible. 2) X-ray methods have been set up which permit a quantitative study of the defects in the compounds at room temperature and allow following the change in the structure from 300 K to about 10 K especially the variation of the identity period along the c axis perpendicular to the graphite sheets. 3) The in-plane electrical resistivity of several compounds was measured as a function of both stage and temperature, by using a contectless inductive method.
