Pressure-assisted fabrication of organic light emitting diodes with MoO3 hole-injection layer materials
In this study, pressures of∼ 5 to∼ 8 MPa were applied to organic light emitting diodes
containing either evaporated molybdenum trioxide (MoO 3) or spin-coated poly (3, 4-
ethylene dioxythiophene) doped with poly (styrene sulphonate)(PEDOT: PSS) hole-injection
layers (HILs). The threshold voltages for both devices were reduced by about half, after the
application of pressure. Furthermore, in an effort to understand the effects of pressure
treatment, finite element simulations were used to study the evolution of surface contact …
