Anomalous enhancement of thermal radiation transport by quasidisorder
Cheng-Long Zhou, Xin-Yu Jia, Shui-Hua Yang +4
The transition from order to disorder is conventionally regarded as detrimental to solid-state heat transfer in classical wave and quasiparticle systems. In striking contrast, we s…
Role of interface mixing on coherent heat conduction in periodic and aperiodic superlattices
Theodore Maranets, Evan Doe, Yan Wang
Superlattices (SLs) can induce phonon coherence through the periodic layering of two or more materials, enabling tailored thermal transport properties. While most theoretical studi…
How phonon coherence develops and contributes to heat conduction in periodic and aperiodic superlattices
Theodore Maranets, Yan Wang
This work investigates the impact of device length on thermal conductivity in periodic and aperiodic superlattices (SLs). While it is well known that thermal conductivity in aperio…
Spectral heat flux redistribution upon interfacial transmission
Haoran Cui, Theodore Maranets, Tengfei Ma +1
In nonmetallic crystals, heat is transported by phonons of different frequencies, each contributing differently to the overall heat flux spectrum. In this study, we demonstrate a s…
