Thermal conductivity minimum of graded superlattices due to phonon localization
Yangyu Guo, Marc Bescond, Zhongwei Zhang +4
The Anderson localization of thermal phonons has been shown only in few nano-structures with strong random disorder by the exponential decay of transmission to zero and a thermal c…
Anharmonic phonon-phonon scattering at interface by non-equilibrium Green's function formalism
Yangyu Guo, Zhongwei Zhang, Marc Bescond +3
The understanding and modeling of inelastic scattering of thermal phonons at a solid/solid interface remain an open question. We present a fully quantum theoretical scheme to quant…
Interpretation of apparent thermal conductivity in finite systems from equilibrium molecular dynamics simulations
Haikuan Dong, Shiyun Xiong, Zheyong Fan +3
We propose a way to properly interpret the apparent thermal conductivity obtained for finite systems using equilibrium molecular dynamics simulations (EMD) with fixed or open bound…
Influence of Boundaries and Thermostatting on Nonequilibrium Molecular Dynamics Simulations of Heat Conduction in Solids
Zhen Li, Shiyun Xiong, Charles Sievers +7
Nonequilibrium molecular dynamics (NEMD) has been extensively used to study thermal transport at various length scales in many materials. In this method, two local thermostats at d…
Native surface oxide turns alloyed silicon membranes into nanophononic metamaterials with ultra-low thermal conductivity
Shiyun Xiong, Daniele Selli, Sanghamitra Neogi +1
A detailed understanding of the relation between microscopic structure and phonon propagation at the nan oscale is essential to design materials with desired phononic and thermal p…
MoS2 Heterostructure with Tunable Phase Stability: Strain Induced Interlayer Covalent Bond Formation
Bin Ouyang, Shiyun Xiong, Zhi Yang +2
Due to the distinguished properties offered by different structural phases of monolayer MoS2, phase engineering design are urgently required for achieving switchable structural pha…
