Real-time tracking of interfacial charge dynamics in a metal–dielectric Janus nanocluster

Key Points

• Investigating the charge dynamics during plasmon excitation in a metal-dielectric nanocluster.
• Utilized Au-Si Janus nanoclusters to study interfacial charge dynamics.
• Conducted real-time tracking of electron behavior during plasmon excitation.
• Demonstrated near-Fermi-level electron injection into silicon.
• Showed that hybridized interface states bypass traditional hot-electron transport mechanisms.
