Efficiency droop in InGaN/GaN multiple quantum well light-emitting diodes with nonuniform current spreading [PDF]

open access: yes, 2011
We demonstrate that the efficiency droop phenomenon in multiple quantum well InGaN/GaN light-emitting diodes (LEDs) may be connected to the current crowding effect.

Surface plasmon polariton modification in top-emitting organic light-emitting diodes for enhanced light outcoupling [PDF]

open access: yes, 2014
We report on the enhanced light outcoupling efficiency of monochrome top-emitting organic light-emitting diodes (OLEDs). These OLEDs incorporate a hole transport layer (HTL) material with a substantially lower refractive index (∼ 1:5) than the emitter ...
