QLED Efficiency Droop — Auger Recombination in Quantum-Dot LEDs

Interactive quantum-dot LED device simulator: injected electrons and holes recombine radiatively, via Auger three-carrier loss, or via trap capture — watch external efficiency rise then droop as drive current climbs, following the real ABC rate-equation model.

Quantum-dot displays get their saturated color from electroluminescence: electrons and holes injected from opposite electrodes recombine inside the quantum-dot emissive layer, and each captured exciton either emits a photon or loses its energy as heat. This simulator models that competition with the real ABC rate equation — trap-assisted (A·n), radiative (B·n²) and Auger (C·n³) recombination — solving for the steady-state carrier density at a chosen drive current and showing the resulting internal quantum efficiency rise and then droop as current climbs, exactly as measured in real high-brightness QLED and quantum-dot laser devices.

Inside a quantum-dot LED, injected electrons and holes recombine radiatively, via three-carrier Auger loss, or via trap capture — watch internal quantum efficiency rise then droop as drive current climbs, following the real ABC rate-equation model used in QLED and laser-diode physics.
