International audience; By exploiting experimentally measured optical properties of Silicon Carbide (SiC) at different temperatures, we recently showed based on a numerical analysis, that when SiC grating is heated, the position of its emissivity pea

Thermal rectification of far-field heat currents is experimentally demonstrated by exploiting the metal-insulator transition of ${\mathrm{VO}}_{2}$ driving the significant temperature variations of its emissivity, within a narrow interval of temperat

International audience; We extend the application of the nonlocal theory of Mahan and Claro [Phys. Rev. B 38, 1963 (1988)] to solve the steady-state Boltzmann-Peierls transport equation within the framework of the single mode relaxation time approxim

We propose in this article a method to conceive radiative coolers that are reflective in the solar spectrum and emissive in the transparency window of the atmosphere (8–13 µm). We choose an approach combining thermal control capacities of gratings

We analyze and discuss the fundamental behavior of the nonlocal/nonlinear contributions to heat transport by phonons in bulk cubic semiconductor (SC) crystals subject to large temperature gradients. The calculation approach is based on solving steady

We demonstrate that the energy transport of surface phonon-polaritons can be large enough to be observable in a crystal made up of a three-dimensional assembly of nanorods of silicon carbide. The ultralow phonon thermal conductivity of this nanostruc
