Which mechanism causes diminished blue light output in blue LEDs at elevated current densities?

💡 Explanation

Increased carrier concentration at high currents boosts the Auger recombination process, a three-particle interaction, reducing band-to-band radiative transitions because Auger is non-radiative; therefore, less blue light is emitted, rather than a change of band-to-band or recombination pathways affecting efficiency.
