Nano-Interface Engineering To Achieve High-Performance Organic Field-Effect Transistors |
| 초록 |
We investigated bottom- and top-contact OFETs containing various solution-processed organic semiconducting layers fabricated by either spin-casting or inkjet-printing and found that facile chemical coupling of end-functionalized polymers, e.g., dimethylchlorosilane-terminated PS (PS–Si(CH3)2Cl), on source/drain electrodes or gate-dielectrics considerably improved charge transport properties at interfaces between semiconductor and those layers. Specifically, high-performance all-inkjet-printed OFET and organic inverters of 6,13-bis(triisopropylsilylethynyl)pentacene (TIPS-PEN) have been demonstrated on a flexible polymer substrate, using interdigitated S/D structure for drive FET and the chemical coupling method. By introducing the end-functionalized polymer, mobility of TIPS-based devices have been improved by one order of magnitude and interface trap density and potential drop between S/D and semiconducting layer have been reduced by two times. |
