Through insertion of an AlGaN/GaN stack between the u-GaN and n-GaN of GaN-based light-emitting diodes (LEDs), the strain in the epilayer was increased, the dislocation density was reduced. GaN-based LEDs with different Al compositions were compared.
Optical and electrical characteristics of GaN vertical light emitting diode with current block layer
