Recent progress in printable organic field effect transistors

Author affiliations

Abstract

Printable organic field effect transistors (OFETs) have been investigated for more than 20 years, aiming at various emerging applications including flexible/wearable electronics, displays and sensors. Since many comprehensive review articles for this field have been published, here we will focus on the recent progress of this field and address the following issues critical to the future applications of OFETs. First, downscaling technologies for the printing of OFETs with fine resolution will be reviewed. The approaches for short channels and small overlapping as well as patterning of organic semiconductors are summarized. Second, various approaches for realizing low-voltage OFETs will be presented, which are critical to the power consumption of organic devices. Specifically, the operational voltages of OFETs have been successfully decreased to several volts by increasing the gate dielectric capacitance and reducing the sub-gap density of states at the channel. This review will provide guidelines for material design and fabrication processes of OFETs with high performance and advanced applications.
