Imaging the local flow of heat and phonons

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…
