Flexible field-effect transistor arrays with patterned solution-processed organic crystals

Abstract

We demonstrate a fabrication process to develop field-effect transistor arrays based on patterned organic crystals as active semiconductor materials on flexible plastic substrates. Large plate-like organic crystals are produced by a direct spin-coating process on a substrate with patterned wettability. Resulting transistor arrays exhibit high device performance, indicating that the proposed method has great potential in flexible electronics. © 2013 © 2013 Author(s).
