The traditional compromise between stability and efficiency in top‐emitting organic light‐emitting devices has been resolved by using periodically corrugated metallic cathodes. J. Feng, H.‐B. Sun, and co‐workers demonstrate on page 1187 how this new design causes cross‐coupling of the surface plasmon polaritons and the microcavity modes. This design removes the requirement for the cathode material...
The introduction of a periodic corrugation into TOLEDs is demonstrated to be effective in relieving the tradeoff between device stability and efficiency, through the cross coupling of the SPPs associated with the Ag cathode and the microcavity modes. The thickness of the Ag cathode for the corrugated TOLEDs was increased from 20 to 45 nm, and both the device lifetime and efficiency are significantly...
