Non-reciprocal heat transfer advances flexible thermoelectric devices
Jinwen Yang, Wenmei Luo, Hongbin Xu +5
Complex heat dissipation assemblies, inferior performance, and limited flexibility are the primary constraints impeding the wide application and commercialization of conventional f…
Strong phase correlation between diffusons governs heat conduction in amorphous silicon
Zhongwei Zhang, Yangyu Guo, Marc Bescond +3
Understanding the thermal vibrations and thermal transport in amorphous materials is an important but long-standing issue in several theoretical and practical fields. Using direct…
Heat conduction theory including phonon coherence
Zhongwei Zhang, Yangyu Guo, Marc Bescond +3
Understanding and quantifying the fundamental physical property of coherence of thermal excitations is a long-standing and general problem in physics. The conventional theory, i.e.…
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…
Off-center Rattling Triggers High-Temperature Thermal Transport in Thermoelectric lathrates: Non-Perturbative Approach
Qing Xi, Zhongwei Zhang, Tsuneyoshi Nakayama +3
Lattice thermal conductivities of type-I clathrates encapsulating "off-center" guest atoms behave in a way that is sharply different from those of conventional crystals…
