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 …
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).
A 2 year post-doctoral position “Electric-field-activated metal/insulator transitions in Cr-V2O3 investigated by in situ electron spectromicroscopy techniques” is available in the STEM group at the Laboratoire de Physique des Solides, Université Paris-Saclay (Orsay, France)
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 …
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 …
Scientific description The emergency of data-intensive technological areas has generated an urgent need of implementing optical telecommunication functionalities in group IV materials, encouraging researchers to develop novel direct bandgap systems …
Hexagonal boron nitride (h-BN) is an emergent optical material being an indirect bandgap yet with a bright luminescence in the far UV. In the last years a general picture of …
