Effects induced by chemical and structural inhomogeneities on the electronic transport in
organic crystals with the focus on highly-ordered polyacenes are discussed in this paper.
The material class chosen is of great importance as polyacenes are widely studied with
perspectives on applications in thin film devices. As will be shown, the charge carrier
mobility in these long-range ordered molecular systems is limited by chemical impurities
rather than by structural inhomogeneities. Time-of-flight spectroscopy on polyacenes …
