Space Charge Limited Current of high mobility DPP-based polymer |
| 초록 |
Here we studied the charge transport characteristics of widely studied diketopyrrolopyrrole (DPP)-based polymers by using space charge limited current theory. From electric field and temperature dependences of charge transport characteristics in hole-only-device geometry of one of highly conductive DPP-derivatve, we could show that the density of state (DOS) for charge carrier is significantly narrow in the bulk of semiconductors. We argue that the intrinsically narrow DOS in the bulk of PDPPDTSE resulted in significantly superior charge transport behavior, which was not visible in the case of other low mobilty organic semicondcutors containing intrinsically high density of trap states in their bulk. |
