Publication of Pascale Senellart-Mardon’s inaugural lecture at the Collège de France

On the occasion of her appointment to the Collège de France, Pascale Senellart-Mardon, a CNRS researcher at the C2N, is publishing her inaugural lecture, delivered as part of her first professorship. An emblematic tradition of the institution, the inaugural lecture marks the first class given by a newly appointed professor and represents a key moment for the …

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 …
