Overview of electrohydrodynamic deposition for fabricating organic thin film transistors

Abstract

Over the past few decades, organic thin-film transistors (OTFTs) have shown remarkable progress in both device performance and functional applications, owing to the development of organic synthesis and fabrication methods. Electrohydrodynamic (EHD) deposition techniques, including electrospraying, electrospinning, and EHD printing, have emerged as powerful and effective material deposition technologies for electronic device fabrication. These techniques, driven by electric fields, represent a methodological innovation in OTFT fabrication and are currently competitive with other well-established approaches. This study presents a comprehensive overview of EHD deposition for OTFT fabrication, focusing on the high performance and practical applications of these devices, including artificial synapses, memories, and sensors. Our aim is not only to shed light on the existing excellent capabilities but also to stimulate the interest of more researchers and promote further constructive work in this burgeoning research domain.
