Project description
Unprecedented measurement of nanoscale heat transport in materials
Efficient heat management is vital for modern electronics but challenges Fourier’s heat diffusion model, which fails at short time and length scales. The ERC-funded Thermoscopy project aims to investigate the breakdown of Fourier’s law, focusing on the viscous hydrodynamic heat transport regime. To do so, it plans to develop a disruptive SQUID-on-tip thermometer with extreme nanoscale resolution, enabling precise temperature mapping of materials that exhibit non-Fourier behaviour. By comparing experimental data with theoretical predictions, the project aims to uncover microscopic mechanisms of heat transport. The findings will inform a more comprehensive model of heat propagation, advancing the design of energy-efficient materials while deepening the understanding of thermal dynamics in solids.
Objective
Efficient heat management is of paramount importance for modern-day electronics to ensure optimal performance and energy consumption. While Fourier's two-century-old macroscopic model for heat diffusion has served as a valuable tool, in particular for homogeneous solids at room temperature, it does not hold on short time and length scales. Notably, the model assumes that an abrupt and localized temperature perturbation propagates instantly everywhere in the rest of the material.
This project aims to visualize the breakdown of the Fourier's law, paving the way for the development of a more physically satisfying model of heat propagation. My investigation will focus on a specific and very illustrative non-Fourier transport regime that has recently attracted considerable interest in the scientific community: the viscous hydrodynamic regime. To achieve this, I will design and construct a highly sensitive, and spatially resolved thermometer, capable of probing material surfaces with an exceptional resolution to resolve heat propagation at the nanoscale. This tool is a SQUID-on-tip (SOT).
I will carefully scan materials known to exhibit this phenomenon at different scales and play with geometries to enhance or attenuate its effects. By comparing the temperature maps obtained in these regimes with predictions from recent theoretical propositions, I will directly test these models. This project will illuminate the underlying microscopic mechanisms responsible for heat transport, offering crucial insights into the intricate nature of heat propagation in materials at the nanoscale.
THERMOSCOPY represents a groundbreaking initiative that will serve as a stepping stone towards the formulation of a comprehensive physical model for heat propagation in solids beyond the Fourier equation. This will impact the design of future more energy efficient materials.
