Phonon Transport in Large Scale Carbon-Based Disordered Materials: Implementation of an Efficient Order-N and Real-Space Kubo Methodology - Li, Sevinc-li, et al.Li, W.; Sevinc-li, H.; Cuniberti, G.; Roche, S. Phonon Transport in Large Scale Carbon-Based Disordered Ma- terials: ...
interface heat transport becomes more important33. Our work is particularly useful to improve heat dissipation in semiconductor interfaces and metal/semiconductor interfaces at elevated temperatures, especially when the interfaces are formed with low Debye temperature materials such as Au, Ti, and GaAs, ...
Materials with ultrahigh or low thermal conductivity are desirable for many technological applications, such as thermal management of electronic and photonic devices, heat exchangers, energy converters and thermal insulation. Recent advances in simulatio
We believe that this work can be helpful for understanding the signature of the MZM in electron transport through mesoscopic circuits. Introduction Following the successful fabrication of graphene, materials with topological nature have attracted enormous attentions in the field of condensed matter physics...
For example, the lattice thermal conductivity of borophene is reported to be only 2.4% of that of graphene [14]. At the same time, enlightened by the boron monolayers, a great many of boron-based 2D materials have been also extensively studied. To date, many boron-based 2D materials have...
Recent decades have seen tremendous progress in quantitative understanding of phonon transport, which is critical for the thermal management of various functional devices and the proper optimization of thermoelectric materials. In this work, using a first-principles based calculation combined with the non...
Combining Electron-Phonon and Dynamical Mean-Field Theory Calculations of Correlated Materials: Transport in the Correlated Metal Sr$_2$RuO$_4$ Electron-electron ($e$-$e$) and electron-phonon ($e$-ph) interactions are challenging to describe in correlated materials, where their joint effects gov...
Normally these waves, or phonons, are only able to carry heat within, and not between, materials. However, the new research shows that phonons can reach across a gap as small as a nanometer, "tunneling" from one material to another to enhance heat transport. ...
in graphene35,37,38. Most importantly, graphene's transport properties are shown to strongly depend on device size, even for conducting channels as wide as several microns. This should motivate further experiments on graphene and related two-dimensional materials in a macroscopic regime beyond the ...
41. The strength of such conservation of phonon momentum plays a crucial role in the maintenance of hydrodynamic phonon flows and corresponds closely to the viscosity in fluid flows7. On the other hand, carbon-based materials have a relatively high Debye temperature (approximately 2,000 K)42...
