Influence of hole accumulation and leakage at organic/organic interface on device characteristics of organic light-emitting diodes
We measured static characteristics and dynamic behavior of OLED devices. and we confirmed experimentally that device characteristics of OLED devices were dependent on ionization potential of a hole transport layer through a space charge layer formation in the device.
