摘要：
An anthracene-2-thiol treatment of the electrodes in bottom-contact pentacene field-effect transistors is used to improve the performance of organic transistors. Transistors with different channel lengths are prepared in order to separate the sheet resistance from the parasitic series resistance of the contacts and leads. The treatment results in a reduced sheet resistance of more than one order of magnitude whereas the parasistic resistance is nearly unaffected.
