Anomalous Thermal Conductivity Reversal Driven by a Fluctuating Charge Density Wave
Han Huang, Jinghang Dai, Joyce Christiansen-Salameh +14
For more than a century, the lattice thermal conductivity of crystalline solids has been known to decrease with increasing temperature, as the phonons that carry heat scatter more…
Structural, optical, and thermal properties of BN thin films grown on diamond via pulsed laser deposition
Abhijit Biswas, Gustavo A. Alvarez, Tao Li +19
Heterostructures based on ultrawide-bandgap (UWBG) semiconductors (bandgap >4.0 eV), boron nitride (BN) and diamond are important for next-generation high-power electronics. Howeve…
Phase Stability of Hexagonal/cubic Boron Nitride Nanocomposites
Abhijit Biswas, Rui Xu, Joyce Christiansen-Salameh +21
Boron nitride (BN) is an exceptional material and among its polymorphs, two-dimensional (2D) hexagonal and three-dimensional (3D) cubic BN (h-BN and c-BN) phases are most common. T…
Non-linear optics at twist interfaces in h-BN/SiC heterostructures
Abhijit Biswas, Rui Xu, Gustavo A. Alvarez +24
Understanding the emergent electronic structure in twisted atomically thin layers has led to the exciting field of twistronics. However, practical applications of such systems are…
Thermal Transport in Polymers: A Review
Xingfei Wei, Zhi Wang, Zhiting Tian +1
In this article, we review thermal transport in polymers with different morphologies from aligned fibers to bulk amorphous states. We survey early and recent efforts in engineering…
Anharmonicity strongly enhancing thermal interface conductance: A new anharmonic atomistic Green's function formalism
Jinghang Dai, Zhiting Tian
The traditional atomistic Green's function (AGF) was formulated in the harmonic regime, preventing it from capturing the role of anharmonicity in interfacial thermal transport. Inc…
Thermal Conductance Across Harmonic-matched Epitaxial Al-sapphire Heterointerfaces
Zhe Cheng, Yee Rui Koh, Habib Ahmad +17
A unified understanding of interfacial thermal transport is missing due to the complicated nature of interfaces which involves complex factors such as interfacial bonding, interfac…
First-Principles Simulation of Electron Mean-Free-Path Spectra and Thermoelectric Properties in Silicon
Bo Qiu, Zhiting Tian, Ajit Vallabhaneni +5
The mean-free-paths (MFPs) of energy carriers are of critical importance to the nano-engineering of better thermoelectric materials. Despite significant progress in the first-princ…
Thermal Interface Conductance between Aluminum and Silicon by Molecular Dynamics Simulations
Nuo Yang, Tengfei Luo, Keivan Esfarjani +6
The thermal interface conductance between Al and Si was simulated by a non-equilibrium molecular dynamics method. In the simulations, the coupling between electrons and phonons in…
A Comprehensive Review of Heat Transfer in Thermoelectric Materials and Devices
Zhiting Tian, Sangyeop Lee, Gang Chen
Solid-state thermoelectric devices are currently used in applications ranging from thermocouple sensors to power generators in satellites, to portable air-conditioners and refriger…
