Abstract

LEDs and methods of forming LEDs with various structural configurations to mitigate non-radiative recombination at the LED sidewalls are described. The various configurations described include combinations of LED sidewall surface diffusion with pillar structure, modulated doping profiles to form an n-p superlattice along the LED sidewalls, and selectively etched cladding layers to create entry points for shallow doping or regrowth layers.
