Facile Solution Shearing Process for Tuning Crystallinity and Alignment of Organic Semiconductor |
| 초록 |
In this study, we introduce an evaporative assembly method to control the growth of the crystalline organic material for high-quality organic semiconductor patterns. We used flow coating method, which utilizes the phenomenon of the “coffee ring effect” coupled with a convective flow and a controlled stick-slip motion. The crystallinity and alignment of materials impacts on properties of organic field-effect transistors (OFETs). Therefore, to uniform alignment of 6,13-bis(triisopropylsilylethynyl) pentacene (TIPS-PEN) crystal and its size, flow coating was used with different shear stress. The property of crystal were determined with p-OM, pUV, GIWAX, and NEXAFS. Furthermore, through anisotropic p-UV absorption spectrums, one-directional solution shearing causing a crystal aligned morphology was explained. The intensity of crystal was verified its tendency through X-ray diffraction. |
