摘要：
We studied the organic thin-film transistor (OTFT) with a solution based DH4T (alpha,omega-dihexylquaterthiophene) by inkjet printing. In order to improve smoothness and uniformity of DH4T film, the substrate temperature was elevated to 60 degrees C and the printing was performed by an overlapping method. The OTFT on plastic exhibited an on/off current ratio of similar to 10(7) a threshold voltage of -0.25 V, a gate voltage swing of 0.45 V/decade and a field-effect mobility of 0.043 cm(2)/Vs in the saturation region.
