Abstract
The effect of anode surface modification on
performance of uniformly mixed-host (MH) emissive layer
(EML) based organic light emitting diode (OLED) has been
investigated by the numerical simulation. Indium Tin Oxide
(ITO) used as anode in the device. Due to proposed surface
modification technique of ITO, the energy barrier at
anode/organic layer interface is reduced which consummately
enhanced the hole injection rate that leads to balance of carriers
transportation and recombination in the EML. Through the
numerical simulation, the electrical characteristics and internal
device physics of uniform MH-OLED have been analyzed
quantitatively. Calculated current balance factor which is related
to the external quantum efficiency also confirmed the efficiency
enhancement of MH-OLED by the proposed ITO work function
modification technique.
