Improved light output power in GaN-based vertical light-emitting diodes with p-AlInGaN/GaN superlattices
We report the effect of p-type AlGaInN/GaN superlattices (SLs) as electron-blocking layers (EBLs) on the optical properties of vertical light-emitting diodes (VLEDs). Using p-AlGaInN/GaN SLs in VLEDs, we have achieved significant improvements in [...]
