eV electron spectromicroscopy using free-space light
Yves Auad, Eduardo J. C. Dias, Marcel Tencé +7
The synergy between free electrons and light has recently been leveraged to reach an impressive degree of simultaneous spatial and spectral resolution, enabling applications in mic…
Excitonic Absorption Signatures of Twisted Bilayer WSe by Electron Energy-Loss Spectroscopy
Steffi Y. Woo, Alberto Zobelli, Robert Schneider +7
Moiré twist angle underpins the interlayer interaction of excitons in twisted van der Waals hetero- and homo-structures. The influence of twist angle on the excitonic absorption of…
Substrate influence on transition metal dichalcogenide monolayer exciton absorption linewidth broadening
Fuhui Shao, Steffi Y. Woo, Nianjheng Wu +13
The excitonic states of transition metal dichacolgenide (TMD) monolayers are heavily influenced by their external dielectric environment based on the substrate used. In this work,…
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…
