ORGANIC THIN FILM TRANSISTOR AND ORGANIC THIN FILM LIGHT-EMITTING TRANSISTOR

摘要

Disclosed is an organic thin film transistor having excellent stability in the atmosphere and high operating speed. Specifically disclosed is an organic thin film transistor wherein three terminals, namely a gate electrode, a source electrode and a drain electrode, an insulating layer for insulation between the gate electrode and the source electrode/the drain electrode, and an organic semiconductor layer are formed on a substrate and the source-drain current is controlled by a voltage applied to the gate electrode. This organic thin film transistor is characterized in that it further comprises a crystallinity control layer which is composed of a film made from a crystalline compound for controlling the crystallinity of the organic semiconductor layer, and the organic semiconductor layer containing a compound having a heterocyclic group or a compound having a quinone structure is formed on the crystallinity control layer. Also specifically disclosed is an organic thin film light-emitting transistor which is characterized by being composed of the above-described organic thin film transistor wherein one of the source electrode and the drain electrode is composed of a hole injecting electrode and the other is composed of an electron injecting electrode.
