Contact resistance between a metal electrode and an organic active layer is one of the most critical issues in the research and development of organic electronic devices. In the present work, we have fabricated vertical type organic light emitting transistor (OLET) using P3HT as a organic active semiconductor and DMDCNQI as a charge transfer material. The device configuration is ITO/PEDOT:PSS/P3HT/Al gate/P3HT/DMDCNQI/Al. The characteristics of OLET were investigated from the measurement of current-radiance voltage characteristics The needle form of highly conducting DMDCNQI-Al charge transfer complex was obtained, which resulted in the improvement of device performance due to the low organic-metal contact resistance and the high electron transport ability.
