Abstract
Crystal orientation is one of the key parameters for organic field effect transistors (OFETs). Here, DPP-based material with polymer as additive was carried out to fabricate self-assembly organic crystals. By optimizing the blend ratios and concentrations of the solution, well-aligned, high quality crystals were successfully achieved. Optical microscope, scanning electron microscope (SEM) and X-ray diffraction (XRD) were used to characterize the crystals. OFET devices were made using the crystals grown under the optimal condition. Comparing with the devices made by thin films, mobility fabricated by crystals is two order of magnitude higher. We anticipate our finding will promote the development of the field.
