Abstract

Double-heterostructure (DH) organic light-emitting diodes (OLEDs) with thick carrier transport layers based on organic single crystals have been fabricated. Although the total thickness of the organic layers (∼1.4 μm) is one order of magnitude greater than that of conventional thin-film OLEDs, a current density of 100 mA/ cm2 was achieved at 19 V. The major advantage of the single crystal-based DH-OLED was that a very low applied electric field (∼ 104 V/cm) was required for the onset of carrier injection and transport, because of the high carrier mobilities of the single crystal layers.
