Multi-scale APproach for a microscopic underStanding of thermal transport in nanocomposites – MAPS

Submission summary

MAPS proposes a fundamental investigation of thermal transport in nanocomposites, made of the intertwining of different materials on the nanoscale, most promising for thermal management and thermoelectric applications. Their enormous potential still lies unused due to the poor understanding of the microscopic mechanisms ruling thermal transport in heterogeneous systems. Indeed, the many studies of the thermal conductivity, a collective phonon property, remain unable to give insight on what happens to single phonons. MAPS has the ambition to get such understanding by means of an unprecedented multi-scale experimental and theoretical approach, for directly looking at the effect of nanoscale heterogeneities on individual phonons with wavelengths going from micron to sub-nm. By audaciously merging concepts from glass and crystals physics, MAPS proposes a breakthough concept, which will revolutionize thermal engineering, allowing for controlling different phonons for different applications.
