Over the last decade, organic semiconductor thin film transistors have been the focus of many research groups because of their potential application in low-cost integrated circuits. Recently, an organic light-emitting field-effect transistor (OLEFET) was reported. In an OLEFET structure, optimal injection of both holes and electrons into the light-emitting layer are required for maximum quantum efficiency, whereas the gate serves as a controlling electrode. In this work, we achieved an OLFET structure with interdigitated hole-injecting Au and electron-injecting Ca contacts within a submicrometer channel length. Both contacts are bottom contacts to the upper-lying tetracene organic semiconductor. The study of IV-characteristics and light emission from these devices shined light on the underlying physics of the OLEFETs.
