The progress of flexible organic field-effect transistors

Abstract

Flexible organic field-effect transistors (OFETs) have revealed wide prospect in their applications to the flexible display, flexible sensor, flexible radio frequency tag and flexible integrated circuit due to their advantages such as foldability, light weight of device and low-cost fabrication process. On the basis of the introduction of advancement in the study of flexible OFETs in this paper, a broad overview about device structures of flexible OFETs, substrate materials, gate insulating layer materials, active layer materials and electrode materials used for flexible OFETs is given, the fabricating process of flexible OFETs is explained, and the effect of bending pattern on the performance of flexible OFETs is discussed. Finally, the application areas of flexible OFETs are summarized and prospected.
