New holography method with GaN metasurfaces (07/2019)
Conventional hologram designs lack orbital angular momentum selectivity. We designed metasurface holograms consisting of GaN nanopillars with discrete spatial frequency distributions allowing the reconstruction of distinctive orbital angular momentum dependent holographic images. Read more...
European metrology project GIQS kick-off (06/2019)
The European project GIQS (Graphene impedance quantum standard) aims at developing impedance standard easier to operate thanks to the use of graphene on SiC. The consortium, gathering 7 national metrology institutes from European network EURAMET and 2 national metrology institutes form Asia has been reinforced by CRHEA and C2N, who will bring their recognized expertise in graphene growth and processing. The project has just started for 3 years.Read more...

A condensate of polaritons propagating near the speed of light (11/2018)
Physicists from CRHEA, in collaboration with the Pascal Institute and the Nanosciences and Nanotechnologies Center, succeeded in condensing polaritons (half-light/ half-matter particles) in the same quantum state characterized by a very high propagation speed, close to that of the light in the crystal which forms the active zone of the device.Read more...
