C2N organizes its first Rendez-vous Techno

C2N hosts one of the largest academic nanotechnology facilities in Europe. Technology and nanofabrication are therefore at the core of its activities, along with the skills and expertise of those who develop them. This first Tech Meeting, held on Thursday, April 9, was designed as a key moment to highlight these activities and the work carried out within the facility. The event was structured around oral presentations and a poster …

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 …
