Hopping in disordered conducting polymers
Abstract
This paper addresses some important questions concerning hopping conduction in doped conducting polymers, i.e., dimensionality, homogeneity, adiabaticity, Coulomb interactions, and multiphonon character. It will be shown that electron transport in these materials is due to correlated hopping between polaronic clusters. We propose a model which describes quantitatively this process. Conductivity and magnetoresistance measurements performed on disordered polypyrroles doped with polyelectrolytes are presented in support of these ideas. This model emphasizes the role of the dopant as an attractive potential and as a tunneling bridge between neighboring chains. The dopant ions are the source of both the polaronic clusters stability and of the transverse conduction.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
