Vertical Organic Light-Emitting Transistor Using Oriented Molecular Thin Film

Abstract

We proposed a novel organic light-emitting transistors (OLETs) named band conduction based vertical organic light emitting transistor (BCBVOLET). In BCBVOLET, an organic light-emitting diode (OLED) is formed on the vertical organic transistor. The vertical organic transistor we used are originally developed transistor called band conduction based organic transistor (BCBOT). BCBOT allows low-voltage, and high-current operation. As a result of using BCBVOLET, we succeeded to obtain maximum luminance of 600 cd/m² at gate voltage of -2 V. ON / OFF ratio of current density is 10³ at gate voltage of -2 V to 0 V.
