Outline of Final Research Achievements

From the viewpoints of interfacial engineering such as organic/dielectric, organic/organic, guest/host, and organic/ electrode interfaces, the improved external quantum efficiency, field-effect mobility, and emission pattern of top-gate-type organic light-emitting transistors (OLETs) based on ambipolar fluorene-type polymers are investigated. The concept of using an ambipolar bilayer semiconducting heterostructure in OLETs is introduced to provide a new approach to achieve surface emission. The fabrication of various oriented bilayers based on crystalized conjugated polymers is demonstrated by using improved film transfer processes. There are three factors that affect the transport of carriers, i.e., the energy level, threshold voltage, and mobility of each layer for heterostructure OLETs. This work is anticipated to be useful for the development of in-plane light-emitting transistors.
