Akagi ( School of Physics and Nano Systems Institute - National Core Research Center, Seoul National University, Seoul, Korea A. F. Ioffe Physical-Technical Institute, Russian Academy of Sciences, St. Petersburg, | Abstract: | 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) ~ T^alpha with alpha ~ 2.2-7.2 and I(V) ~ V^betta with betta ~ 2-5.7. Both G(T) and I(V) show the features characteristic of 1D systems such as Luttinger liquid or Wigner crystal. The relationship between our results and theories for tunneling in 1D systems is discussed. | Source: | arXiv, cond-mat/0410195 | Other source: | [GID 467866] pmid15600860 | Services: | Forum | Review | PDF | Favorites |
