Fast electronic transport in organic molecular solids
TLDR
In this paper, the principal material property charge carrier mobility is measured, and it is shown that up to 100 cm2/V's can be achieved at room temperature and up to 1.5 cm2V/V at low temperature, if chemical purity and structural order can be brought to a very high level.Abstract:
Starting from the question, what fast electronic transport is based on, and why organic materials in general are more problematic in this respect than typical inorganic ones, methods are introduced that allow to measure the principal material property charge carrier mobility. Some representative experimental results are presented which prove that mobilities around 1–10 cm2/V s can be achieved at room temperature, and more than 100 cm2/V s at low temperature—but only if chemical purity and structural order can be brought to a very high level.read more

Charge carrier transport in organic semiconductors
TL;DR: In this article, a brief review is given on different experimental methods that can either directly measure charge carrier mobilities, or at least lead to an estimate, for high purity single crystals, a steep increase of mobilities towards low temperature with the consequence of nonlinear transport and final velocity saturation at elevated electric fields has been traced back to temperature-dependent electron and hole masses approaching the free electron mass at low temperature.
