Recently, the research team led by Professor Ye Guoyong from the College of Mechanical and Electrical Engineering, concentrating on the research into micro-nano electrofluid jet printing technology and its applications, published a research paper titled "High-performance flexible organic field-effect transistor based on highly ordered poly (3-hexylthiophene) nanowires" in the Chemical Engineering Journal (Chinese Academy of Sciences Q1 TOP journal, IF = 13.4), an international top-tier journal. Additionally, the team received the "Best Researcher Award" granted by SCIENCEFATHER, a global academic organization. Dr. Lu Liangkun, a young teacher from the College of Mechanical and Electrical Engineering, serves as the first author, and Professor Ye Guoyong serves as the corresponding author. Zhengzhou University of Light Industry is credited as the first affiliated institution for this work.

Achieving highly preferred orientation processing of organic semiconductors and high-performance fabrication of organic field-effect transistors are critical challenges in the field of flexible electronics. To tackle the issues, the team proposed a high-resolution nano-confined electrofluid jet printing technique. This approach enabled large-area and high-quality jet printing and manufacturing of typical organic semiconductors such as IDT-BT, PDVT-10, and P3HT, achieving highly consistent, high-resolution jet printing and manufacturing of organic semiconductors on flexible substrates such as PDMS and PI, with the feature size scaled down to 90 nm. The P3HT field-effect transistor devices produced using the electrofluid jet printing process exhibited six-fold higher mobility compared to conventional thin-film devices.

This research was supported by programs such as the Outstanding Youth Fund of Henan Province and the School-level Innovation Team of Zhengzhou University of Light Industry.
