title = "Direct structural mapping of organic field-effect transistors reveals bottlenecks to carrier transport",
abstract = "X-ray microbeam scattering is used to map the microstructure of the organic semiconductor along the channel length of solution-processed bottom-contact OFET devices. Contact-induced nucleation is known to influence the crystallization behavior within the channel. We find that microstructural inhomogeneities in the center of the channel act as a bottleneck to charge transport. This problem can be overcome by controlling crystallization of the preferable texture, thus favoring more efficient charge transport throughout the channel. {\textcopyright} 2012 WILEY-VCH Verlag GmbH & Co.
