Chiroptical interactions, which describe the specific effects arising from the circular polarization of light interacting with chiral materials, are at the core of numerous advances in physics, chemistry, and biology. …
TPX4
The aim of TPX4 is to demonstrate the feasibility of two new types of electron spectro-microscopies: Time- Resolved Cathodoluminescence Excitation spectroscopy (TR-CLE) and High-Resolution Low Energy Electron Microscopy (HRLEEM). Both …
Nanosecond Nanothermometry in an Electron Microscope
Thermal transport in nanostructures plays a critical role in modern technologies. As devices shrink, techniques that can measure thermal properties at nanometer and nanosecond scales are increasingly needed to capture …
Quantum Confined Luminescence in Two Dimensions
The field of nanophotonics has witnessed a surge of interest in localized light emitters, driven by their potential to revolutionize optoelectronic devices. These emitters, including nanoparticles, nanowires, and quantum wells, …
Excitonic absorption signatures of twisted bilayer WSe2 by electron energy-loss spectroscopy
Moiré twist angle underpins the interlayer interaction of excitons in twisted van der Waals hetero- and homostructures. The influence of twist angle on the excitonic absorption of twisted bilayer tungsten …
IMPULSE
The IMPULSE project (In situ MaPping insulator-to-metal transitions by Ultra-high resolution electron SpEctromicroscopy) will develop the characterization tools capable of mapping at sub-nanometer scale the insulating/metallic (I/M) nanodomains induced by insulator-to-metal transition (IMT).
Substrate influence on transition metal dichalcogenide monolayer exciton absorption linewidth broadening
The excitonic states of transition metal dichalcogenide (TMD) monolayers are heavily influenced by their external dielectric environment and depend on the substrate used. In this work, various wide band gap …
QUENOT
The ambition of QUENOT is to overcome several current conceptual and experimental limits in nanooptics using the quantum properties of fast electrons. Indeed, certain key concepts and quantities in nanooptics …
