Observation of multi-directional energy transfer in a hybrid plasmonic-excitonic nanostructure
Tommaso Pincelli, Thomas Vasileiadis, Shuo Dong +15
Hybrid plasmonic devices involve a nanostructured metal supporting localized surface plasmons to amplify light-matter interaction, and a non-plasmonic material to functionalize cha…
Scalable multicomponent spectral analysis for high-throughput data annotation
Rui Patrick Xian, Ralph Ernstorfer, Philipp Michael Pelz
Orchestrating parametric fitting of multicomponent spectra at scale is an essential yet underappreciated task in high-throughput quantification of materials and chemical compositio…
Machine Learning on Neutron and X-Ray Scattering
Zhantao Chen, Nina Andrejevic, Nathan Drucker +8
Neutron and X-ray scattering represent two state-of-the-art materials characterization techniques that measure materials' structural and dynamical properties with high precision. T…
Direct measurement of key exciton properties: energy, dynamics and spatial distribution of the wave function
Shuo Dong, Michele Puppin, Tommaso Pincelli +15
Excitons, Coulomb-bound electron-hole pairs, are the fundamental excitations governing the optoelectronic properties of semiconductors. While optical signatures of excitons have be…
A quantitative comparison of time-of-flight momentum microscopes and hemispherical analyzers for time- and angle-resolved photoemission spectroscopy experiments
J. Maklar, S. Dong, S. Beaulieu +7
Time-of-flight-based momentum microscopy has a growing presence in photoemission studies, as it enables parallel energy- and momentum-resolved acquisition of the full photoelectron…
Observation of an excitonic Mott transition through ultrafast core--conduction photoemission spectroscopy
Maciej Dendzik, R. Patrick Xian, Enrico Perfetto +19
Time-resolved soft-X-ray photoemission spectroscopy is used to simultaneously measure the ultrafast dynamics of core-level spectral functions and excited states upon excitation of…
