Flexible Organic Thin‐Film Transistors with Silk Fibroin as the Gate Dielectric

Silk fibroin, one of the silk proteins produced by the silk work, is shown to be an excellent gate dielectric material for pentacene organic thin-film transistors (OTFTs). The pentacene OTFT described exhibits a very high field-effect mobility value of 23.2 cm2 V−1 s−1 and a low operating voltage of –3 V. This, combined with its advantages of low cost and light weight, confers on it great potential for high-speed flexible electronics applications.
