| Summary: | Some years ago Donovan and Wilson (1981) concluded that carrier motion on a single chain of the quasi-one-dimensional polymer crystal PDA-TS exhibits highly unusual features. From the electric field dependence of the peak photocurrent and carrier generation rate they concluded that carriers had an ultra-high mobility and a low-field saturated drift velocity. The authors report new measurements in the t- alpha time-dependent domain and at the same time propose a transport model to explain the data. They show that both the t- alpha decay law and the sublinear field scaling of the effective drift velocity can be associated with one and the same phenomenon: One-dimensional carrier drift in the presence of strongly scattering defects. |
