Revealing Additional Size-Dependent Defect Suppression Channels Governing Detectivity in InAs Colloidal Quantum Dot Photodiodes
Published in Nano Letters 2025, 25 (48), 16862–16868, 2025
HDR-EQE measurements of InAs CQD photodiodes reveal that trap densities decrease with increasing nanocrystal size beyond simple surface-to-volume scaling, and that today’s devices are primarily limited by contact and interface properties rather than intrinsic trap-mediated recombination.
