Regulating a Charge Injection of Organic Field-Effect Transistors by Incorporation of Reductive Interlayers |
| 초록 |
For enhancing the electronics behavior of the organic semiconductors, efficient injection of favorable charge carriers and blocking the undesired counter-charge should be achieved. To this end, we introduced a reductive interlayer in staggered organic field-effect transistors. Solution-processed reducing agents enabled efficient electron injection characteristics by remarkably changing the work function of the metal electrode so that lowering the contact resistance. Therefore, it makes changes in OFET properties markedly by controlling the electron injection while blocking the counter charge carriers between bottom-contact electrodes and the active layer. Ambipolar or n-type organic semiconductors showed high electron mobility with shifted threshold voltages in a positive direction. The principle of this phenomena by adding the reductive interlayer is studied and further applied for the development of high performance printed and flexible electronic devices and integrated circuits. |
