Anomalous EL–PL Lifetime Inversion in Silicon Quantum-Dot Light-Emitting Diodes

Abstract Diamond-cubic silicon is a promising quantum-dot material for sustainable optoelectronics owing to its abundance, nontoxicity, and size-tunable photoluminescence (PL). However, silicon quantum-dot light-emitting diodes (Si-QLEDs) suffer from severe efficiency roll-off at...
