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…
Prominent phonon transmission across aperiodic superlattice through coherent mode-conversion
Theodore Maranets, Yan Wang
In both particle and wave descriptions of phonons, the dense, aperiodically arranged interfaces in aperiodic superlattices are expected to strongly attenuate thermal transport due…
Influence of Spatial Coherence on Phonon Transmission across Aperiodically Arranged Interfaces
Theodore Maranets, Milad Nasiri, Yan Wang
In this study, we employ the atomistic wave-packet method to directly simulate coherent phonon transport and scattering dynamics in an aperiodic superlattice structure with aperiod…
