Efficiency droop halved in cubic- versus hexagonal-phase InGaAlN LEDs
What happened
Research indicates cubic-phase InGaAlN LEDs can halve efficiency droop compared to traditional hexagonal-phase variants. This addresses a key performance limitation in nitride-based LEDs, which suffer from significant efficiency loss at high currents. Neutral: This is a long-term R&D milestone with no immediate impact on trading or supply of commercial LED components.
