PhD - Metamaterial for thermal fluxes control

Université Bourgogne Franche-Comté (UBFC)

Besancon, France

Metamaterials are artificial composite materials designed to achieve properties that are inaccessible naturally. In this project, they will combine thermal conductor (metal or silicon) and insulating (dielectric or air) materials in order to control thermal fluxes at the micron scale.

The successful candidate will participate on the design, fabrication and characterization of these metamaterials.

The conception will be made with transformation methods and finite element simulations. Fabrication will be performed at the MIMENTO (Besançon) and ARCEN-Carnot (Dijon) clean room facilities. 3D printing at the micron scale with two-photon polymerization technology (nanoscribe) will also be applied.

For characterization, several complementary tools such as a thermal camera, femtosecond thermoreflectance set-ups, scanning thermal microscope or quantitative phase imaging will be used. The candidate will also participate on the improvement of some set-ups. An example of thermal concentrator with no perturbation of the heat flow that could be fabricated and tested, can be find here [Q. Ji et al., International Journal of Heat and Mass Transfer 169 (2021) 120948]
