Effects of Interlayer Coupling on Hot Carrier Dynamics in Graphene-derived van der Waals Heterostructures
Prineha Narang, Litao Zhao, Steven Claybrook +1
Graphene exhibits promise as a plasmonic material with high mode confinement that could enable efficient hot carrier extraction. We investigate the lifetimes and mean free paths of…
Experimental and ab initio ultrafast carrier dynamics in plasmonic nanoparticles
Ana M. Brown, Ravishankar Sundararaman, Prineha Narang +3
Ultrafast pump-probe measurements of plasmonic nanostructures probe the non-equilibrium behavior of excited carriers, which involves several competing effects obscured in typical e…
Plasmonic Hot Electron Transport Driven Site-Specific Surface-Chemistry with Nanoscale Spatial Resolution
Emiliano Cortés, Wei Xie, Javier Cambiasso +5
Nanoscale localization of electromagnetic fields near metallic nanostructures underpins the fundamentals and applications of plasmonics. The unavoidable energy loss from plasmon de…
Ab initio phonon coupling and optical response of hot electrons in plasmonic metals
Ana M. Brown, Ravishankar Sundararaman, Prineha Narang +2
Ultrafast laser measurements probe the non-equilibrium dynamics of excited electrons in metals with increasing temporal resolution. Electronic structure calculations can provide a…
