摘要：
We have studied the performance improvement of organic thin-film transistor (OTFT) with a solution based TIPS pentacene (6,13-bis(triisopropylsilyiethynyl)pentacene) by inkjet printing. The TIPS pentacene with 1.0 wt.% solution in 1,2-dichlorobenzene was used for printing of an active layer of OTFT. The OTFT printed at room temperature shows a shoulder-like behavior but it disappears for the OTFT printed at the substrate temperature of 60 degrees C. The OTFT on plastic exhibited an on/off current ratio of similar to 10(7), a threshold voltage of -2.0 V, a gate voltage swing of 0.6 V/decade and a field-effect mobility of 0.24 cm(2)/VS in the saturation region.
