Oral (Non-Student) / Orale (non-étudiant(e))

To date, there are very few all-optical techniques, if any, that are suitable for the purpose of acquiring, with nanoscale lateral resolution, quantitative maps of the thermal conductivity and thermal expansivity of 2D materials and nanostructured thin films, despite huge demand for nanoscale thermal management, for example in designing integrated circuitry for power electronics. Here, we...

Oral Competition (Graduate Student) / Compétition orale (Étudiant(e) du 2e ou 3e cycle)

The intense confinement of electromagnetic fields between metallic bispheres remains a subject of ongoing technological interest. Similarly, light can be concentrated into near-flied subwavelength hotspots in dimers of high refractive index dielectric resonators. Micro-resonators made of silicon and germanium are often exploited in forming exceedingly strong axial hotspots in dimers at visible...
