Recent progress in organic field‐effect transistor‐based integrated circuits

Abstract

Organic integrated circuits are undergoing rapid development with the extensive research on organic semiconducting materials and the performance improvement of organic field-effect transistors. Organic integrated circuits not only cover all the major circuit types, their complexity, degree of integration, and performance have also been improved in recent years. In this review, recent advances in the design and fabrication of integrated circuits based on organic field-effect transistors are reported. The circuits are categorized into digital and analog, which are discussed in detail centering on the structure, fabrication process, and performance. In addition, progress in the modeling and simulation of organic integrated circuits are discussed as well, as they are key issues for the future development of organic electronics.

“…Organic semiconductor materials have attracted increasing attention from the scientific community in the past three decades. Conjugated polymers and small molecules have great potential as active materials for designing next-generation electronic devices such as organic field-effect transistors, 1 organic photodetectors, 2 organic solar cells, 3 etc. Conjugated small molecules have several advantages as compared to polymers including high purity and a well-defined structure and composition, thus providing higher reproducibility of electrical parameters of devices.…”

Synthesis and Effect of the Structure of Bithienyl-Terminated Surfactants for Dielectric Layer Modification in Organic Transistor

“…An organic field-effect transistor (OFET) efficiency is given mainly by the first two layers of the organic semiconductor at the dielectric surface where the charge transfer takes place [ 2 ]. Therefore, the quality of the interface between OS and insulator has a crucial role [ 3 , 4 , 5 , 6 ]. It should be mentioned here that this complex topic includes the impact of various effects.…”
