Experimental and ab initio ultrafast carrier dynamics in plasmonic nanoparticles

24 Dec 2016 Brown Ana M. Sundararaman Ravishankar Narang Prineha Schwartzberg Adam M. Goddard William A. III Atwater Harry A.

Ultrafast pump-probe measurements of plasmonic nanostructures probe the non-equilibrium behavior of excited carriers, which involves several competing effects obscured in typical empirical analyses. Here we present pump-probe measurements of plasmonic nanoparticles along with a complete theoretical description based on first-principles calculations of carrier dynamics and optical response, free of any fitting parameters...
