Organic Thin Film Transistors for Large Area Electronics

TLDR

Organic thin‑film transistors have seen significant performance improvements in recent years. This review aims to provide new insights into OTFT conduction mechanisms, performance characteristics, and modeling opportunities. It examines how research has shifted from novel chemical structures to fabrication technologies that optimize morphology and structural order, with chapters on vacuum‑deposited and solution‑processed organic semiconducting films. The review highlights substantial progress in the emerging field of n‑type OTFTs. A figure depicting a pentacene film edge on SiO₂ illustrates the morphology issue.

Abstract

Organic thin-film transistors (OTFTs) have lived to see great improvements in recent years. This review presents new insight into conduction mechanisms and performance characteristics, as well as opportunities for modeling properties of OTFTs. The shifted focus in research from novel chemical structures to fabrication technologies that optimize morphology and structural order is underscored by chapters on vacuum-deposited and solution-processed organic semiconducting films. Finally, progress in the growing field of the n-type OTFTs is discussed in ample detail. The Figure, showing a pentacene film edge on SiO2, illustrates the morphology issue.
