TU-3 is a n-type organic semiconductor material with long term (year-long) stability in air. And it can be deposited from its solutions to form felxible integrated circuits in either 2D or 3D configurations.
This material achieves a high electron mobility of 2.3 cm2/Vs or more in transistors, making it highly suitable for this application. The mobility of amorphous silicon used in general LCDs and other applications is about 0.5-1cm2/Vs.

Direct printing of thin-film transistors has enormous potential for ubiquitous and lightweight wearable electronic applications. However, advances in printed integrated circuits remain very rare. Here we present a three-dimensional (3D) integration approach to achieve technology scaling in printed transistor density


Professor Tokito and Professor Takeda share their new materials, device architecture design principles, and performance optimization protocols for printed and solution-processed, low-cost, highly flexible, organic electronic devices.
