Plasmon-induced hot-carriers generated through Landau damping underpin applications in plasmonic optoelectronics, energy conversion, and photocatalysis. However, it remains unclear whether these carriers retain the spatial localization of their parent plasmon modes or rapidly lose this spatial memory through ultrafast scattering and transport. Here, we experimentally probe the spatial and temporal dynamics of plasmon-induced hot-carriers in a strongly confined plasmonic structural color...
