The development of organic devices with ionic liquids

Abstract

The electric double layer gating technique using ionic liquids, which allows an increase in the capability of typical field effect doping by two orders of magnitude, opens up a new avenue, not only to novel physics of solid-state materials but also to potential applications for organic electronics. Here we report on high-performance organic field-effect transistors and new applications for organic light-emitting diodes with ionic-liquid electrolytes.
