摘要：

We report the first low temperature measurements of IN characteristics of polyacetylene nanofibers. Our data provide (i) no temperature dependence below 10-30K, (ii) no significant change of MR in magnetic field up to H=6T, to within the accuracy of the data. These are signatures of a novel conduction mechanism: the creation of charged soliton-antisoliton pairs by quantum-mechanical tunneling.
