@article{Gonzlez1993ELECTROSTATICSI, title={ELECTROSTATIC SCREENING IN FULLERENE MOLECULES}, author={J W Gonz{\'a}lez and Francisco Guinea and Mar'ia A. H. Vozmediano}, journal={Modern Physics Letters B}, year={1993}, volume={07}, pages={1593-1599} }

The screening properties of fullerene molecules are described by means of a continuum model which uses the electronic wave functions of planar graphite as a starting point. The long-distance behavior of the system gives rise to a renormalizable theory, which flows towards a nontrivial fixed point. Its existence implies an anomalous dielectric constant. The screening properties are neither metallic nor insulating. Alternatively, the intramolecular screening is obtained from a simple… Expand
