Diketopyrrolopyrrole based organic field effect devices: Investigation of various substrates and substrate temperatures on device efficiency |
| 초록 |
Non-Functionalized soluble diketopyrrolopyrrole (DPP) core is used as the p-type semiconductor material in organic field effect transistor(OFET). We report the characteristic of various alkyl chains based soluble DPP derivatives and investigated their behaviors in OFET. The characteristics have been analysis by using UV-vis and X-ray diffraction, cyclic voltammetry (CV) and atomic force microscopy (AFM). Especially, DPP-R12 was investigated in detail. In top contact OFET, two type of gate insulator is prepared, cross-linked poly(4-vinylphenol) and OTS/SiO2. The performance of devices and the surface characteristic according to three different temperatures (25°C, 60°C, and 90°C) is investigated. When substrate temperature was 90°C, OFETs fabricated on CL-PVP shows the maximum performance with hole mobility of 0.013 cm2V-1s-1. In addition, stability characteristic was checked and the inverters using DPP-R12 were fabricated and their static and dynamic characteristics are analyzed. |
