Nano Film Morphology Engineering
Fabrication of high quality semiconductor films is one of the most important field in electronic devices. As an alternative of vacuum system, our group developed the Marangoni effect for fabrication of high quality semiconductor films. When the solution is dropped into liquid, thin film can be formed by the difference in tension. Adjusting solvent or additive and post processes allows to control the film morphology.
Organic Field Effect Transistors
Solution processable organic field-effect transistors (OFETs) have gained considerable attention as promising building blocks for a wide range of next-generation flexible electronic applications. Our group developed a general method to form high-quality organic films on a liquid substrate based on the spontaneously spreading (SS) phenomenon and applied this process to fabricate solution-processable OFETs by using a dry process to directly transfer polymer films formed on a water surface onto polymeric dielectric layers. By taking advantage of the proposed process, we successfully demonstrated flexible OFETs exhibiting high electrical properties despite the mild thermal treatment.
