Interface-Electrolyte Gating of Defect-Selective Recombination Tunes Charge-Carrier Dynamics and Photoelectrochemical Activity.
Defect-mediated recombination in oxide photoelectrodes is widely treated as an intrinsic loss pathway, yet its selective control remains largely unexplored. Here, we demonstrate that oxygen-vacancy-mediated recombination in ZnO can be effectively modulated through interface engineering and electrolyte-dependent kinetic...
