In this internship, we will explore a novel technique that allows us to directly probe the thermal behavior of nanomaterials at unprecedented scales. Recent advances in event-based direct detectors in electron microscopy [1] open new possibilities. At the LPS Orsay, a new method based on synchronized focused-photon excitation and electron scattering of nanostructures [2] allows for temperature measurements with nanosecond and nanometer resolution [3]. In this M2 internship we will explore this new technique to measure the thermal transport properties of nanoscale metallic nanowires. This internship will involve the production of metallic nanowires using electron beam lithography and metal evaporation, the realization of electron spectroscopy in a state-of-the-art electron microscope, including world-wide unique light injection experiments, and data modeling for thermal transport. The ideal candidate will have a strong background in solid-state physics, with a focus on experimental techniques. Experience with data analysis tools (specifically Python) is essential. Familiarity with thermal transport theory and modeling would be a plus. References [1] Y. Auad et al., Ultramicroscopy 239 (2022) 113539; Y. Auad, et al., Ultramicroscopy 257 (2024) 113889. [2] Y.
