摘要：

We report our transport studies in quasi-one-dimensional (1D) conductors -helical polyacetylene fibers doped with iodine-and the data analysis for other polymer single fibers and tubes. We found that at 30 K<T<300 K, the conductance and the current-voltage characteristics follow the power law G(T)proportional toT(alpha) with alphasimilar to2.2-7.2 and I(V)proportional toV(beta) with betasimilar to2-5.7. Both G(T) andI(V) show the features characteristic of 1D systems such as a Luttinger liquid or Wigner crystal. The relationship between our results and theories for tunneling in 1D systems is discussed.
