Problématique
Understanding heat transfer at the nanoscale remains one of the greatest intellectual challenges in the field of thermal dynamics, by far the most relevant under an applicative standpoint. When thermal dynamics is confined to short time and length scales and/or at low temperatures, non-diffusive heat transport regimes set in, ranging from ballistic to hydrodynamic. Depending on the system, different heat carriers may be involved such as electrons, phonons and spins just to mention few of them. Within these regimes, the validity of Fourier’s law, the milestone constitutive relation describing diffusive heat transport, fails, thus calling for novel heat transfer characterization techniques and interpretative schemes. Under an applicative standpoint, managing non-Fourier heat transport is a key-factor for micro- and nano-devices operations and their further downscaling.
This thematic day focuses on recent developments in the general topic of non-Fourier heat transfer at the nanoscale. The scope is to bring together different views on this emerging topic, merging experimental investigations and theoretical studies. This meeting is an opportunity for the community to share ideas and foster new collaborations. We wish you pleasant scientific discussions in a relaxed and friendly environment.
