Insertion of an organic interlayer for hole current enhancement in inverted organic light emitting devices

Soon Mi Park, Yoon Hak Kim, Yeonjin Yi, Hyoung-Yun Oh, and Jeong Won Kim We report the enhancement of hole current density in the hole transport part of an inverted top-emission organic light emitted diode by applying an organic insertion layer of 1,4,5,8,9,11-hexaazatriphenylene-hexacarbonitrile (HAT-CN). Poor hole transporting performance of Al/4,4-bis(N-phenyl-1-napht ... [Appl. Phys. Lett. 97, 063308 (2010)] published Fri Aug 13, 2010.
