If you have a question about this talk, please contact Dr Miguel Navarro-Cia. Zoom Meeting ID: 879 3387 9601. Passcode: 9a976i The decay of localized surface plasmons in metallic nanoparticles can result in the generation of energetic or “hot” electrons and holes. These carriers can be harvested and harnessed for applications in photovoltaics, photocatalysis and light sensing. To optimize hot carrier production in devices, a detailed theoretical understanding of the relevant microscopic processes, including light-matter interactions, plasmon decay and hot electron thermalization, is needed. In the first part of my talk, I will describe a material-specific theory of hot-carrier generation in metallic nanoparticles. This approach combines a classical description of the light field with a quantum-mechanical treatment of the electrons. Combining this approach with materials screening techniques has enabled the discovery of efficient photocatalysts based on bi-metallic core-shell nanoparticles. In the second part of my talk, I will describe our efforts to develop a fully quantum-mechanical description of plasmon decay which can be used to describe hot carrier generation in a nanoparticle with a single plasmon quantum.
