Recent advanced applications of ion-gel in ionic-gated transistor

Abstract

Diversified regulation of electrons have received much attention to realize a multi-functional transistor, and it is crucial to have a considerable control over the charge carriers in transistors. Ionic gel, as the dielectric material in transistors, facilitates a large capacitance, and high induced-carrier concentrations. This review presents the recent progress in ionic-gated transistors (IGTs) that have good mechanical stability as well as high physical and chemical stability. We first briefly introduce the various applications of IGTs in sensors, neuromorphic transistors, organic transistor circuits, and health detection. Finally, the future perspectives of IGTs are discussed and some possible solutions to the challenges are also proposed.
