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…

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…
