摘要：

A model proposed for the conduction band of alkali-metal-doped C60, which allows for experimentally relevant orientational disorder, is further analyzed. Transport properties are calculated by evaluation of Kubo-Greenwood formulas on finite systems. The residual resistivity is close to 400-mu-OMEGA-cm, the thermal conductivity satisfies the Weidemann-Franz law; and the thermopower varies as the inverse of the conduction bandwidth with a known coefficient, making possible quantitative estimates of the density of states. The comparison with experimental results appears favorable.
