Nanoscale Heat Engineering for Advanced Technology

Description du projet

Gestion de la chaleur dans l’électronique à l’échelle nanométrique

La miniaturisation des composants électroniques à l’échelle atomique pose des problèmes de gestion de la chaleur, car une dissipation thermique inefficace peut réduire les performances et gaspiller de l’énergie. Soutenu par le programme Actions Marie Skłodowska-Curie, le projet nanoHEAT explore le potentiel des matériaux 2D pour concevoir des nanodispositifs thermiquement efficaces et activement réglables. Ces matériaux possèdent des propriétés uniques, notamment des caractéristiques électroniques, optiques et thermiques extraordinaires, idéales pour contrôler les flux de chaleur. En étudiant le comportement de matériaux 2D sélectionnés dans des conditions extrêmes, nanoHEAT vise à développer des hétérostructures optimisées qui améliorent le transport de la chaleur. Cette recherche ouvrira la voie à une électronique à haut rendement énergétique et consolidera la position de l’UE dans le secteur de la photonique tout en faisant progresser les carrières scientifiques dans le domaine de la nanophotonique.

Objectif

The miniaturization trend of electronic components down to atomic length scales generates new challenges in the management of heat at the nanoscale. Efficient heat dissipation in electronic devices leads to lower energy waste and improved operation efficiency, thus contributing in a decisive way to environmentally sustainable technological developments. The nanoHEAT project aims to leverage the unique properties of 2D materials for the design of thermally efficient and actively tunable nanodevices, due to their compactness, extraordinary electronic, optical, and thermal properties, and support of exotic polaritonshybrid light/matter electromagnetic modes that propagate at the surface of materials and play a crucial role in heat transport. Using advanced nanophotonics theory, nanoHEAT will start by studying in detail the behavior of selected 2D materials under extreme conditions of confinement, temperature, and external stimuli (such as magnetic fields or drift currents). After carefully selecting which materials (and their combinations) display the most advantageous thermal capabilities, optimized heterostructures based on these materials and noble metals will be explored as versatile building blocks for realistic setups with enhanced radiative and conductive heat transport in the nanoscale. External stimuli, in combination with other active elements such as quantum scatterers, will be used as knobs to control heat flow in these systems. Carried out at the University of Southern Denmark together with a widely experienced research team, this project will allow the fellow to advance his scientific career by harnessing new skills in nanophotonics, expanding his collaboration network, and acquiring complementary competencies in teaching, communication, and outreach, and research leadership. It will also contribute to solidifying the EUs strategic position in the photonics industry and paving the way towards new generations of energy-efficient electronic devices.
