A MODEL OF FULLERENE CONDUCTANCE

An attempt has been made to describe fullerene conductance on the basi s of the additive conductance Dresselhaus-Dresselhaus model for graphi te, taking into account the topology of a fullerene molecule in the cr ystal lattice. It has been shown that fullerene conductance is related to the sigma(c) component of the conductance of graphite through the relation sigma(full) approximate to 10(-2) sigma(c)(graph), because on ly 1 out of 60 atoms in a fullerene molecule Is Involved in creating a path of conductance between electrodes and the ratio of fullerene to graphite density is rho(full)/rho(graph) = 0.74. Total resistivity of fullerene is determined by resistivites of individual fullerene balls. Doping, like in graphite, causes an increase in the conductivity of i ntercalated Me(x)C(60) for low value of x. Copyright (C) 1996 Elsevier Science Ltd
