Nanodiamond grain boundaries and lattice expansion drive Silicon vacancy emission heterogeneity
Daniel K. Angell, Shuo Li, Hendrik Utzat +8
Silicon-vacancy (SiV) centers in diamond are promising candidates as sources of single-photons in quantum networks due to their minimal phonon coupling and narrow optical linew…
Dynamic lattice distortions driven by surface trapping in semiconductor nanocrystals
Burak Guzelturk, Benjamin L. Cotts, Dipti Jasrasaria +26
Nonradiative processes limit optoelectronic functionality of nanocrystals and curb their device performance. Nevertheless, the dynamic structural origins of nonradiative relaxation…
Driving energetically-unfavorable dehydrogenation dynamics with plasmonics
Katherine Sytwu, Michal Vadai, Fariah Hayee +4
Nanoparticle surface structure and geometry generally dictate where chemical transformations occur, with the low-coordination-number, high-radius-of-curvature sites being energetic…
Fluorescence-Detected Circular Dichroism of a Chiral Molecular Monolayer with Dielectric Metasurfaces
Michelle L. Solomon, John M. Abendroth, Lisa V. Poulikakos +2
Strong enhancement of molecular circular dichroism has the potential to enable efficient asymmetric photolysis, a method of chiral separation that has conventionally been impeded b…
Surface-Enhanced Circular Dichroism spectroscopy on periodic dual nanostructures
Jon Lasa-Alonso, Diego R. Abujetas, Alvaro Nodar +5
Increasing the sensitivity of chiral spectroscopic techniques such as circular dichroism (CD) spectroscopy is a current aspiration in the research field of nanophotonics. Enhancing…
Electron and Light Induced Stimulated Raman Spectroscopy for Nanoscale Molecular Mapping
Amr A. E. Saleh, Daniel K. Angell, Jennifer A. Dionne
We propose and theoretically analyze a new vibrational spectroscopy, termed electron- and light-induced stimulated Raman (ELISR) scattering, that combines the high spatial resoluti…
