Enhancement Of Efficiency Of GaN-on-GaN LED By Wet Etching Roughening On N-Face Gan Substrate
It is well-known that GaN-on-GaN LEDs have lower dislocation density compared to GaN-on-sapphire LEDs. Nonetheless, the overall efficiency of the GaN-on-GaN LEDs is still lower than the GaN-on-sapphire LEDs. The problem is associated to total internal reflection effect which is higher in the LEDs....
