Which outcome occurs when an electron's confinement energy surpasses the quantum dot bandgap within an LED?

💡 Explanation

Enhanced Auger recombination increases because energy gets transferred to another electron via Coulomb interaction instead of light emission. Therefore, it decreases radiative efficiency, rather than increasing it; alternative processes alter the efficiency via different mechanisms.
