Extreme longitudinal thermal conductivity and non-diffusive heat transport in isotopic hBN

Researchers from C2N and collaborators at Neel lab., MPQ lab, L2C lab. and Kansas university report record thermal transport properties in isotopically purified hexagonal boron nitride (hBN), a two-dimensional insulating material of major interest for thermal dissipation and thermal anisotropy. By combining microfabricated suspended devices with Raman thermometry (Fig a and b), the team demonstrates an in-plane thermal conductivity exceeding 1650 W·m⁻¹·K⁻¹ at room temperature, among the highest values …

C2N Highlights 2025 : a year in review

Here is our Highlights 2025 report. This booklet presents an overview of the activities carried out and the research conducted within the laboratory. It also highlights the key institutional and scientific moments of 2025. These highlights once again demonstrate C2N’s position as a leading laboratory at the local, national, and international levels, made possible by the dedication and commitment of all its teams: researchers, professors, associate professors, engineers, technicians, administrative …
