Polaron excitations in doped C60: Effects of disorders

Abstract

Effects on C60 by thermal fluctuations of phonons, misalignment of molecules in a crystal, and other intercalated impurities are simulated by disorder potentials. The SSH model for doped C60 is solved with gaussian bond and site disorders. Polarons and dimerizations in lightly doped cases (C60^{-1,-2}) are relatively stable against disorders, indicated by peak structures in distribution functions of bond length and charge density.
