Theory of radial oscillations in metal nanoparticles driven by optically induced electron density gradients

Robert Salzwedel, Andreas Knorr, Dominik Hoeing +2

We provide a microscopic approach to describe the onset of radial oscillation of a silver nanoparticle. Using the Heisenberg equation of motion framework, we find that the coupled…

Time-resolved single-particle x-ray scattering reveals electron-density as coherent plasmonic-nanoparticle-oscillation source

D. Hoeing, R. Salzwedel, L. Worbs +18

Dynamics of optically-excited plasmonic nanoparticles are presently understood as a series of sequential scattering events, involving thermalization processes after pulsed optical…

3D diffractive imaging of nanoparticle ensembles using an X-ray laser

Kartik Ayyer, P. Lourdu Xavier, Johan Bielecki +34

We report the 3D structure determination of gold nanoparticles (AuNPs) by X-ray single particle imaging (SPI). Around 10 million diffraction patterns from gold nanoparticles were m…

Impact of Substrate on Tip-enhanced Raman Spectroscopy --- A Comparison of Frequency Domain Simulations and Graphene Measurements

Hudson Miranda, Cassiano Rabelo, Luiz Gustavo Cancado +7

Tip-enhanced Raman spectroscopy (TERS) has reached nanometer spatial resolution for measurements performed at ambient conditions and sub-nanometer resolution at ultra high vacuum.…

Phonon-assisted Auger enables ultrafast charge transfer in CdSe Quantum Dot/Organic Molecule

Zhi Wang, Mona Rafipoor, Pablo García Risueño +4

Charge transfer between photoexcited quantum dots and molecular acceptors is one of the key limiting processes in most applications of colloidal nanostructures, most prominently in…
