The third-order polarizability of the substitute-doped fullerenes

Abstract

The third-order polarizabilities of substituted fullerenes are calculated by using the Su - Schrieffer - Heeger (SSH) model and the sum-over-states (SOS) approach. Numerical results show that there are larger static polarizabilities and resonant peaks in than those in X. For , the highest peak value of (at eV) is found to be about two orders larger than that for B, which may be important for its practical use.
