High external quantum efficiency in InGaN-based green micro-light emitting diodes at ultra-low current density by removing pre-wells

InGaN-based green light-emitting diodes with different pre-well numbers were grown by an organometallic vapor phase epitaxy deposition method on patterned sapphire substrates. Micro-LED chips with a size of 17 × 20 μm ^2 were fabricated, and a peak external quantum efficiency (EQE) of 39% was achiev...
