Plasmonic nanocrystals with complex shapes for photocatalysis and growth: Contrasting anisotropic hot-electron generation with the photothermal effect
Artur Movsesyan, Eva Yazmin Santiago, Sven Burger +4
In plasmonics, and particularly in plasmonic photochemistry, the effect of hot-electron generation is an exciting phenomenon driving new fundamental and applied research. However,…
Temporal plasmonics: Fano and Rabi regimes in the time domain in metal nanostructures
Oscar Ávalos-Ovando, Lucas V. Besteiro, Zhiming Wang +1
The Fano and Rabi models represent remarkably common effects in optics. Here we study the coherent time dynamics of plasmonic systems exhibiting Fano and Rabi resonances. We demons…
Comments on ""Hot" electrons in metallic nanostructures -- non-thermal carriers or heating?" and "Assistance of metal nanoparticles to photo-catalysis -- nothing more than a classical heat source"
Alexander O. Govorov, Lucas V. Besteiro
The authors of preprint arXiv:1810.00565 and paper in Light: Science & Applications (2019), Y. Dubi and Y. Sivan, made several wrong and inconsistent comments on several of our pap…
Circular Dichroism of Chiral Molecules in DNA- Assembled Plasmonic Hotspots
Luisa M. Kneer, Eva-Maria Roller, Lucas V. Besteiro +3
The chiral state of a molecule plays a crucial role in molecular recognition and biochemical reactions. Because of this and owing to the fact that most modern drugs are chiral, the…
Understanding Hot-Electron Generation and Plasmon Relaxation in Metal Nanocrystals: Quantum and Classical Mechanisms
Lucas V. Besteiro, Xiang-Tian Kong, Zhiming Wang +2
Generation of energetic (hot) electrons is an intrinsic property of any plasmonic nanostructure under illumination. Simultaneously, a striking advantage of metal nanocrystals over…
What's so Hot about Electrons in Metal Nanoparticles?
Gregory V. Hartland, Lucas V. Besteiro, Paul Johns +1
Metal nanoparticles are excellent light absorbers. The absorption processes create highly excited electron-hole pairs and recently there has been interest in harnessing these hot c…
