Enhanced Electrical Performance of Organic Field-Effect Transistors by Solvent Exposure of Semiconductor Layers |
| 초록 |
The effects of the solvent on the structure and morphology of solution-phase semiconductors containing bulky triisopropylsilylethynyl(TIPS) groups were investigated during the solution-processed passivation of organic field-effect transistors (OFETs) by using X-ray diffraction (XRD) and atomic force microscopy (AFM). Exposure of the semiconductor layers to ethanol improved their molecular ordering and crystallinity, thus leading to enhanced electrical characteristics of the OFETs. The interface-trap density of the OFETs decreased from 3.0x1012 to 4.13x1011 cm-2 after ethanol exposure. |
