The Origin of the Glass-like Thermal Conductivity in Crystalline Metal-Organic Frameworks
Yanguang Zhou, Yufei Gao, Sebastian Volz
It is textbookly regarded that phonons, i.e., an energy quantum of propagating lattice waves, are the main heat carriers in perfect crystals. As a result, in many crystals, e.g., b…
Quantum mechanical modeling of anharmonic phonon-phonon scattering in nanostructures
Yangyu Guo, Marc Bescond, Zhongwei Zhang +3
The coherent quantum effect becomes increasingly important in the heat dissipation bottleneck of semiconductor nanoelectronics with the characteristic size shrinking down to few na…
Revisiting thermal conductivity and interface conductance at the nanoscale
B. Davier, P. Dollfus, S. Volz +2
A semi-analytical model for studying thermal transport at the nanoscale, able to accurately describe both the effect of out of equilibrium transport and the thermal transfer at int…
Thermal Transfer in Amorphous Superionic Systems
Yanguang Zhou, Sebastian Volz
Using direct atomic simulations, the vibration scattering time scales are characterized, and then the nature and the quantitative weight of thermal excitations are investigated in…
Self-synchronization of thermal phonons at equilibrium
Zhongwei Zhang, Yangyu Guo, Marc Bescond +3
Self-synchronization is a ubiquitous phenomenon in nature, in which oscillators are collectively locked in frequency and phase through mutual interactions. While self-synchronizati…
A generalized decay law for particle- and wave-like thermal phonons
Zhongwei Zhang, Yangyu Guo, Marc Bescond +3
Our direct atomic simulations reveal that a thermally activated phonon mode involves a large population of elastic wavepackets. These excitations are characterized by a wide distri…
