Graded-host phosphorescent light-emitting diodes with high efficiency and reduced roll-off
(A I P Publishing LLC, 2012)
We demonstrated graded-host phosphorescent organic light-emitting diodes with high efficiency and reduced efficiency roll-off. The emissive layer of the graded host device consists of both electron and hole transport type ...
A charge inverter for III-nitride light-emitting diodes
(American Institute of Physics Inc., 2016)
In this work, we propose a charge inverter that substantially increases the hole injection efficiency for InGaN/GaN light-emitting diodes (LEDs). The charge inverter consists of a metal/electrode, an insulator, and a ...
