Phonon-mediated thermal transport at cryogenic temperatures: physical insights and device applications
At cryogenic temperatures, thermal transport is predominantly governed by long-wavelength acoustic phonons with exceptionally long intrinsic mean free paths, leading to significant departures from the diffusive transport behavior characteristic of room temperature. Understanding these transport mechanisms is essential...
