Recent progress of high performance organic thin film field-effect transistors

Abstract

During the past few decades, thousands of organic semiconductors have been designed and synthesized for organic thin-film transistors (OTFTs). However, most of them exhibit non-ideal performance. After carefully reviewing recent OTFTs with high performance, e.g., OTFTs with mobility over 1.0 cm² V⁻¹s⁻¹, guidelines for device fabrication are highlighted, especially the importance in finding promising compounds and regulating molecular properties for OTFTs, as well as in modifying surfaces of dielectric and electrodes for high-quality devices.
