Cathodoluminescence excitation spectroscopy: nanoscale imaging of excitation pathways
Nadezda Varkentina, Yves Auad, Steffi Y. Woo +9
Following the lifespan of optical excitations from their creation to decay into photons is crucial in understanding materials optical properties. Macroscopically, techniques such a…
Aluminum Cayley trees as scalable, broadband, multi-resonant optical antennas
Thomas Simon, Xiaoyan Li, Jérôme Martin +4
An optical antenna can convert a propagative optical radiation into a localized excitation, and reciprocally. Although optical antennas can be readily created using resonant nanopa…
Three dimensional vectorial imaging of surface phonons
Xiaoyan Li, Georg Haberfehlner, Ulrich Hohenester +3
While phonons and their related properties have been studied comprehensively in bulk materials, a thorough understanding of surface phonons for nanoscale objects remains elusive. I…
Can Copper Nanostructures Sustain High-Quality Plasmons?
Vahagn Mkhitaryan, Katia March, Eric Tseng +10
Silver is considered to be the king among plasmonic materials because it features low inelastic absorption in the visible and infrared (vis-IR) spectral regions compared to other m…
Fast reconstruction of atomic-scale STEM-EELS images from sparse sampling
Etienne Monier, Thomas Oberlin, Nathalie Brun +3
This paper discusses the reconstruction of partially sampled spectrum-images to accelerate the acquisition in scanning transmission electron microscopy (STEM). The problem of image…
Spatial and spectral dynamics in STEM hyperspectral imaging using random scan patterns
Alberto Zobelli, Steffi Y. Woo, Luiz H. G. Tizei +6
The evolution of the scanning modules for scanning transmission electron microscopes (STEM) has realized the possibility to generate arbitrary scan pathways, an approach currently…
Point defect states emergence in a plasmonic crystal
Hikaru Saito, Hugo Lourenço-Martins, Noémie Bonnet +6
Plasmonic crystals are well known to have band structure including a bandgap, enabling the control of surface plasmon propagation and confinement. The band dispersion relation of b…
Tailored nanoscale plasmon-enhanced vibrational electron spectroscopy
Luiz H. G. Tizei, Vahagn Mkhitaryan, Hugo Lourenço-Martins +12
Vibrational optical spectroscopies can be enhanced by surface plasmons to reach molecular-sized limits of detection and characterization. The level of enhancement strongly depends…
Direct evidence of tungsten clustering in WVO thin films and its effect on the metal-to-insulator transition
Xiaoyan Li, Alexandre Gloter, Alberto Zobelli +4
Substitutional tungsten doping of VO thin films and its effect on the metal-to-insulator transition are investigated by means of X-ray diffraction, Cs-corrected scanni…
