Beyond Fourier Thermal Management at the Nanoscale

Résumé

In this proceeding, we show diverse non Fourier effects that have been obtained with Molecular Dynamics simulations using silicon nanostructures and nanostructured materials. First, thermal rectification is observed in silicon nanowires with asymmetric amorphous shells. We then show that it is possible to design a pass band filter for phonons using a similar structure. Finally, phonon diffraction is obtained using two crystalline silicon blocks connected by silicon nanochannels.
