Abstract
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 = 15-100 nm). We found that at 30 K < T < 300 K the conductance and the current-voltage characteristics follow the power-law: G(T) â Tα and I(V) â Vβ with α = 2.2-7.2 and β = 2-5.7, 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.
