Organic Light-Emitting Field-Effect Transistors: Device Geometries and Fabrication Techniques

Abstract

Organic light-emitting transistors (OLETs), as novel and attractive kinds of organic electronic devices, have gained extensive attention from both academia and industry. The unique device architectures can simultaneously combine the electrical switching functionality of organic field-effect transistors and the light generation capability of organic light-emitting diodes in a single device, thereby holding great promise for reducing the complicated processes of next-generation pixel circuitry. This review involves the design, fabrication, and applications of OLETs with a comprehensive coverage of this field with the aim to give a deep insight into the intrinsic mechanisms of devices. Challenges and future prospects of OLETs are also discussed.
