Abstract :
Light Emitting Diodes (LEDs) have become an attractive concept as efficient light sources. In this contribution, the electro-optical performance of Ill-nitride based core-shell nanorod LEDs is investigated by detailed simulation. In contrast to their planar counterparts, they possess increased active region area on small footprint, non-polar active regions with c-plane vertical growth, and form horizontal two-dimensional active photonic crystals for the optical extraction process.
