Phonon Scattering in the Complex Strain Field of a Dislocation
Yandong Sun, Yanguang Zhou, Ramya Gurunathan +5
Strain engineering is critical to the performance enhancement of electronic and thermoelectric devices because of its influence on the material thermal conductivity. However, curre…
How Thermal Annealing Process Determines the Inherent Structure Evolution in Amorphous Silicon: An Investigation from Atomistic Time Scales to Experimental Time Scales
Yanguang Zhou
The annealing treatment in the advanced manufacturing process, e.g., laser-assisted manufacturing, determines the final state of glasses which is critical to its thermal, electrica…
Probing the Phonon Mean Free Paths in Dislocation Core by Molecular Dynamics Simulation
Yandong Sun, Yanguang Zhou, Ming Hu +3
Thermal management is extremely important for designing high-performance devices. The lattice thermal conductivity of materials is strongly dependent on the structural defects at d…
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…
Strong phonon localization in PbTe with dislocations and large deviation to Matthiessen's rule
Yandong Sun, Yanguang Zhou, Jian Han +5
Dislocations can greatly enhance the figure of merit of thermoelectric materials by prominently reducing thermal conductivity. However, the evolution of phonon modes with different…
Atomistic Simulation of Phonon and Magnon Thermal Transport across the Ferro-Paramagnetic Transition
Yanguang Zhou, Julien Tranchida, Yijun Ge +2
A temperature-dependent approach involving Green-Kubo equilibrium atomic and spin dynamics (GKEASD) is reported to assess phonon and magnon thermal transport processes accounting f…
