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, Álvaro 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…
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…
Luminescence properties of closely packed organic color centers grafted on a carbon nanotube
Antoine Borel, Federico Rapisarda, Stephen K. Doorn +2
We report on the photo-luminescence of pairs of organic color centers in single-wall carbon nanotubes grafted with 3,5 dichlorobenzene. Using various techniques such as intensity c…
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…
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…
Onset of optical-phonon cooling in multilayer graphene revealed by RF noise and black-body radiation thermometries
D. Brunel, S. Berthou, R. Parret +8
We report on electron cooling power measurements in few-layer graphene excited by Joule heating by means of a new setup combining electrical and optical probes of the electron and…
Exploiting one-dimensional exciton-phonon coupling for tunable and efficient single-photon generation with a carbon nanotube
Adrien Jeantet, Yannick Chassagneux, Théo Claude +4
Condensed-matter emitters offer enriched cavity quantum electrodynamical effects due to the coupling to external degrees of freedom. In the case of carbon nanotubes a very peculiar…
Unifying the low-temperature photoluminescence spectra of carbon nanotubes: the role of acoustic phonon confinement
Fabien Vialla, Yannick Chassagneux, Robson Ferreira +6
At low temperature the photoluminescence of single-wall carbon nanotubes show a large variety of spectral profiles ranging from ultra narrow lines in suspended nanotubes to broad a…
Photo-draining and slow capture of carriers in quantum dots probed by resonant excitation spectroscopy
Hai Son Nguyen, Gregory Sallen, Marco Abbarchi +5
We investigate experimentally and theoretically the resonant emission of single InAs/GaAs quantum dots in a planar microcavity. Due to the presence of at least one residual charge…
Temperature dependence of exciton recombination in semiconducting single-wall carbon nanotubes
S. Berger, C. Voisin, G. Cassabois +3
We study the excitonic recombination dynamics in an ensemble of (9,4) semiconducting single-wall carbon nanotubes by high sensitivity time-resolved photo-luminescence experiments.…
