Inkjet Printed Silver Electrodes for Organic Thin-Film Transistors

Abstract

Inkjet printing high resolution electrodes is crucial for printing low-cost and high performance organic thin film transistors (OTFTs). This paper reviews our recent studies on inkjet printing high resolution silver electrodes (both narrow electrodes and small gaps between the electrodes as OTFT channel length) from either a silver complex composition or a silver nanoparticles ink for OTFTs. High performance devices with a narrow electrode (< 50 um) and a small channel length (∼ 10 um) were demonstrated. OTFTs with these printed silver electrodes exhibited high performance.
