Abstract:

During recent years, the development of processing techniques from simple spin coating to more sophisticated methods has resulted in a more advanced control over the macroscopic order and molecular alignment on the surface of organic semiconductors. As a consequence, the charge carrier transport in the thin surface layer and thus the performance of electronic devices, especially field-effect transistors, has been significantly enhanced. Moreover, comprehensive understanding of the relation between molecular design, processing parameters, molecular ...
