Phonon Dominated Thermal Transport in Metallic Niobium Diselenide from First Principles Calculations
(MDPI, 2023)
Niobium diselenide (NbSe2) is a layered transition metal dichalcogenide material which possesses unique electrical and superconducting properties for future nanodevices. While the superconducting, electrical, and bulk ...
Thermal transport in a 2D stressed nanostructure with mass gradient
(Instituto de Física de Líquidos y Sistemas Biológicos, 2015-04)
Inspired by some recent molecular dynamics (MD) simulations and experiments on suspended graphene nanoribbons, we study a simplified model where the atoms are disposed in a rectangular lattice coupled by nearest neighbor ...
Evidence of scattering effects on the thermal transport in indium-doped CdTe films
(Institute of Physics, 2013-01-16)
Thermal conductivity of hot pionic medium due to pion self-energy for pi sigma and pi rho loops
(World Scientific Publ Co Pte Ltd, 2015-07-01)
The thermal conductivity of pionic medium has been evaluated with the help of its standard expression from the relaxation time approximation, where inverse of pion relaxation time or pion thermal width has been obtained ...
Thermal transport in one-dimensional spin heterostructures
(American Physical Society, 2009-07)
We study heat transport in a one-dimensional inhomogeneous quantum spin-1/2 system. It consists of a finite-size XX spin chain coupled at its ends to semi-infinite XX and XY chains at different temperatures, which play the ...
Extreme Nonreciprocal Near-Field Thermal Radiation via Floquet Photonics
(American Physical Society, 2021-05)
By using Floquet driving protocols and interlacing them with a judicious reservoir emission engineering, we achieve extreme nonreciprocal thermal radiation. We show that the latter is rooted in an interplay between a direct ...
The Scattering of Phonons by Infinitely Long Quantum Dislocations Segments and the Generation of Thermal Transport Anisotropy in a Solid Threaded by Many Parallel Dislocations
(MDPI, 2020)
A canonical quantization procedure is applied to the interaction of elastic waves-phonons-with infinitely long dislocations that can oscillate about an equilibrium, straight line, configuration. The interaction is implemented ...
