One-dimensional transport in polymer nanowires
We report the results of transport studies of quasi-one-dimensional (1D) conductors  helical polyacetylene fibers doped with iodine and the data analysis for other polymer single fibers and tubes (diameter=15100nm). We found that at 30K<T<300K the conductance and the currentvoltage characteristics follow the power-law: G(T)?T? and I(V)?V? with ?=2.27.2 and ?=25.7, respectively. Both G(T) and I(V) show some features characteristic of one-dimensional systems such as Luttinger liquid or Wigner crystal. The relationship between our results and theories for tunneling in one-dimensional systems is discussed.
