High-performance and multifunctional organic field-effect transistors

Organic field-effect transistors (OFETs) refer to field-effect transistors that use organic semiconductors as channel materials. Owing to the advantages of organic materials such as solution processability and intrinsic flexibility, OFETs are expected to be applicable in emergent technologies including wearable electronics and sensors, flexible displays, internet-of-things, neuromorphic computing, etc. Improving the electrical performance and developing multifunctionalities of OFETs are two major and closely relevant aspects for OFETs-related research. The former one aims for investigating the device physics and expanding the horizons of OFETs, while the later one is critical for leading OFETs into practical and emergent applications. The development in each of the two aspects would undoubtfully promote the other and bring more confidence for future development of OFETs. Hence, this review is divided into two parts that respectively summarize the recent progress in high-performance OFETs and multifunctional OFETs.
