Optical properties of single CsPbBr3 perovskite quantum dots synthesized by a modified ligand-assisted reprecipitation method
Marina Cagnon Trouche, Ernest Ruby, Margaux Cartier +5
Colloidal perovskite quantum dots (pQDs) are promising quantum light emitters, and investigations at the single pQD scale have so far relied mostly on hot-injection synthesis, whic…
Localized emission in MoSe monolayers on GaN nanopillars
Abderrahim Lamrani Alaoui, Ãlvaro Moreno, Maximilian Heithoff +12
Solid-state quantum emitters (QEs) in two-dimensional semiconductors offer compact, chip-compatible sources for quantum photonics. In transition-metal dichalcogenides (TMDs), nanop…
Cavity quantum electrodynamics with single perovskite quantum dots
Zakaria Said, Marina Cagnon Trouche, Antoine Borel +5
Quantum emitters of single indistinguishable photons play a key role in quantum technologies. Among condensed matter systems, colloidal perovskite quantum dots have emerged as prom…
Electroluminescence and Energy Transfer Mediated by Hyperbolic Polaritons
L. Abou-Hamdan, A. Schmitt, R. Bretel +26
Under high electrical current, some materials can emit electromagnetic radiation beyond incandescence. This phenomenon, referred to as electroluminescence, leads to the efficient e…
The optical absorption in indirect semiconductor to semimetal PtSe2 arises from direct transitions
Marin Tharrault, Sabrine Ayari, Mehdi Arfaoui +12
is a van der Waals material transitioning from an indirect bandgap semiconductor to a semimetal with increasing thickness. Its absorption threshold has been conjectur…
Impact of bright-dark exciton thermal population mixing on the brightness of CsPbBr nanocrystals
Mohamed-Raouf Amara, Caixia Huo, Christophe Voisin +2
Understanding the interplay between bright and dark exciton states is crucial for deciphering the luminescence properties of low-dimensional materials. The origin of the outstandin…
