- Suppressed thermal transport in mathematically inspired 2D heterosystemsIn two-dimensional (2D) heterosystems, the contribution of coherent phonon transport makes superlattices with high interface density exhibit unexpected high thermal conductivity. Herein, inspired by mathematics, we demonstrate efficient suppression of phonon thermal transport… Read more: Suppressed thermal transport in mathematically inspired 2D heterosystems
- Assessing phonon coherence using spectroscopyAs a fundamental physical quantity of thermal phonons, temporal coherence participates in a broad range of thermal and phononic processes, while a clear methodology for the measurement of phonon coherence… Read more: Assessing phonon coherence using spectroscopy
- Observation of phonon Poiseuille flow in isotopically purified graphite ribbonsIn recent times, the unique collective transport physics of phonon hydrodynamics motivates theoreticians and experimentalists to explore it in micro- and nanoscale and at elevated temperatures. Graphitic materials have been… Read more: Observation of phonon Poiseuille flow in isotopically purified graphite ribbons
- Resonant Thermal Transport Driven by Surface Phonon-Polaritons in a Cylindrical CavityThe axial thermal conductance of a cylindrical cavity supporting the propagation of hybridized guided modes along its interface with SiO22 is quantified and analyzed as a function of its radius and… Read more: Resonant Thermal Transport Driven by Surface Phonon-Polaritons in a Cylindrical Cavity
- Parabolic mirrors collimating and focusing fluxes of thermal phononsManipulating heat fluxes at the nanoscale has become increasingly important in modern microelectronics. However, many methods of heat manipulations rely on complex nanofabrication. Here, we propose simple designs for collimation… Read more: Parabolic mirrors collimating and focusing fluxes of thermal phonons
