Thermal rectification due to phonon confinement in nanoparticles
Alexej D. Semenov, Mariia Sidorova, Alessio Zaccone +1
We demonstrate that thermal rectification can arise at the contact between two spherical nanoparticles of identical material but different size due to the geometric confinement of…

Low-Temperature Heat Transport under Phonon Confinement in Nanostructures
M. Sidorova, A. D. Semenov, A. Zaccone +5
Heat transport in bulk materials is well described using the Debye theory of 3D vibrational modes (phonons) and the acoustic match model. However, in cryogenic nanodevices, phonon…
