When the Nanowires from C2N lead an Enhancement of Single-Photon Purity and Coherence of III-Nitride Quantum Dot with Polarization-Controlled Quasi-Resonant Excitation
Materials Science is at the heart of new technological developments. These last years, the III-Nitride Team from the Materials Department's has mastered the growth InGaN/GaN NWs, with InGaN insertions characterized by high homogeneity, indium contents of up to 50% …

Strong light-matter coupling observed with a nanoscale thermal transducer in a single nano-cavity
Researchers at C2N, in collaboration with University of Rome (Italy), Istituto Italiano di Technologia (Italy), Rice University (USA) and University Leeds (UK), have demonstrated an original nanospectroscopy technique that permits the study of the light−matter interaction in single subwavelength-sized …

Hydrogen sorption in yttrium-based getter thin films
We investigated the sorption of hydrogen by yttrium-based getters for their application to vacuum wafer-level packaging of microelectromechanical systems. Thin alloy films were co-evaporated under ultra-high vacuum on silicon wafers. Getters were activated by annealing during one hour under …

Toward integrated photonic systems for laser beam control
Free-space laser beams are of core importance in many fast-growing technologies, including optical communications, 3D imaging and mapping, interconnects, and augmented reality. However, state-of-the-art solutions that allow to generate and control such beams typically comprise mechanical assemblies, moving parts …

A multi-frequency passive resonator for the non-contact and non-invasive monitoring of organic materials
The non-invasive characterization of organic matter is a major issue in many fields of activity, such as agriculture, food industry and health. The complex permittivity being a relevant indicator of the physiological state of organic matter, especially in the …
