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…
Exciton mapping at subwavelength scales in two-dimensional materials
Luiz H. G. Tizei, Yung-Chang Lin, Masaki Mukai +5
Spatially resolved EELS has been performed at diffuse interfaces between MoS and MoSe single layers. With a monochromated electron source (20 meV) we have successfully prob…
Probing plasmon-NV coupling at the nanometer scale with photons and fast electrons
H. Lourenço-Martins, M. Kociak, S. Meuret +5
The local density of optical states governs an emitters lifetime and quantum yield through the Purcell effect. It can be modified by a surface plasmon electromagnetic field, but su…
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…
Visualizing plasmon-exciton polaritons at the nanoscale using electron microscopy
Andrew B. Yankovich, Battulga Munkhbat, Denis G. Baranov +7
Polaritons are compositional light-matter quasiparticles that have recently enabled remarkable breakthroughs in quantum and nonlinear optics, as well as in material science. Despit…
