摘要：

A solvent-assisted drop-casting technique is introduced for the active layer formation in fabricating polymer thin-film transistors (TFTs). This method allows one to lower the rate of film formation (or deposition) of polymer semiconductor and to use a higher temperature, both factors contributing to better ordering of the semiconducting polymer. A notable increase in mobility results when the technique is applied to fabricating the polymer TFT. More important is the stability of the device that the method provides. (C) 2006 Elsevier B.V.
