Magic angle in thermal conductivity of twisted bilayer graphene
Yajuan Cheng, Zheyong Fan, Tao Zhang +5
We report a local minimum in thermal conductivity in twisted bilayer graphene (TBG) at the angle of 1.08, which corresponds to the 'magic angle' in the transition of severa…
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…
Mechanical Tuning of Thermal Transport in a Molecular Junction
Qian Li, Ivan Duchemin, Shiyun Xiong +2
Understanding and controlling heat transport in molecular junctions would provide new routes to design nanoscale coupled electronic and phononic devices. Using first principles ful…
Functionalization mediates heat transport in graphene nanoflakes
Haoxue Han, Yong Zhang, Zainelabideen Y. Mijbil +9
Self-heating is a severe problem for high-power microelectronic devices. Graphene and few-layer graphene have attracted tremendous attention for heat removal thanks to their extrao…
Classical to quantum transition of near-field heat transfer between two nanoparticles
Shiyun Xiong, Kaike Yang, Yuriy A. Kosevich +4
Heat transfer between two silica clusters is investigated by using the non-equilibrium Green's function method. In the gap range between 4 Å and three times the cluster size, the t…
