Enhanced Light Extraction of Flip-Chip Mini-LEDs with Prism-Structured Sidewall
Current solutions for improving the light extraction efficiency of flip-chip light-emitting diodes (LEDs) mainly focus on relieving the total internal reflection at sapphire/air interface, but such methods hardly affect the epilayer mode photons.We demonstrated that the prism-structured sidewall based Pleated on tetramethylammonium hydroxide (TMAH)
