current control element, organic light-emitting diode, a manufacturing method of manufacturing methods and organic light-emitting diode of the current control element

摘要

Is to provide a device which is capable of modulating the flow of charge carriers of one kind [1] challenges. Apparatus for [SOLUTION] charge-carrier modulation is a current control device having a semiconductor layer stacked. An electron transport layer disposed between the hole transport layer and the second hole transport layer of the first and the organic semiconductor layers stacked is, an electron transport layer and the second electron transport layer or the first / and a hole transporting layer disposed between. Each intermediate layer is a modulation layer having a contact portion to the modulation voltage. By modulating voltage is applied, the flow of the modulation current through the modulation layer is generated. This flow of modulation current, the flow of the component currents flowing through the modulation layer to a respective electron transport layer or the second hole transporting layer to the second electron transport layer of the first or the first hole transport layer control.
