Electrical Properties of Triisopropylsilyl Pentacene Organic Thin-Film Transistors by Ink-Jet Method

چکیده
We fabricated triisopropylsilyl (TIPS) pentacene organic thin-film transistors (OTFTs) by inkjet printing method and investigated their electrical properties. The film morphology of TIPS pentacene layer and the field-effect mobility of OTFTs were greatly affected by choice of the solvent which TIPS pentacene was dissolved in. Especially the boiling point of a solvent was a critical factor that determines the electrical properties of TIPS pentacene OTFTs. The field-effect mobility of an OTFT fabricated from anisole solution (boiling points of 155C) was 0.04 cm V s while that of OTFT from chlorobenzene solution (boiling points of 132C) was 0.01 cmVs, suggesting that a solvent with a higher boiling point is preferable in the fabrication of ink-jet printed OTFTs.
