Towards nanoscale efficient light sources

Unveiling the Optical Emission Channels of Monolayer Semiconductors Coupled to Silicon Nanoantennas, by J. M. Poumirol et al., ACS Photonics 7 (11), 3106-3115 (2020)

Spectral sorting of single plasmons in a 2D crystalline cavity

" Single plasmon spatial and spectral sorting on a crystalline two-dimensional plasmonic platform " U. Kumar, S. Bolisetty, C. Girard, R. Mezzenga, E. Dujardin and A. Cuche. Nanoscale 12, 13414 (2020)

STM in the spotlight!

Fundamental mechanisms at the origin of the luminescence of semiconducting monolayers have been studied with scanning tunneling microscope-induced light emission technique with unprecedented spatial and spectral resolutions. The luminescence intensity has been enhanced by an order of magnitude by using nanostructured plasmonic substrates.

Controlled functionalization of graphene

Graphene on Cu (111) or on mica can be functionalized in a controlled manner by photo-cycloaddition reactions between a 2D supramolecular layer of a maleimide dienophile and graphene. This reaction disrupts the delocalization of the electrons of graphene by opening a gap of 170 meV in the irradiated zones.

Introducing the "Blue Buggy", our last generation nanocar ready for the next nano Grand Prix

A collaboration of researchers in France and Japan have developed a new family of nanocars ready to compete on a gold surface against the 9 other teams selected for the 2nd Nanocar Race in 2021.
