Janus-induced atomic reconstruction amplifies twist-angle modulation of interlayer thermal transport in moiré bilayers
Bin Xu, Rulei Guo, Jie Sun +8
In two-dimensional moiré bilayers, atomic reconstruction, the spontaneous structural relaxation toward energy-minimizing stacking registries in the near-commensurate regime, can s…

Observation of coherently modulated phonon band and lifetime in superlattice
Yuxuan Liao, Hiroshi Uchiyama, Naomi Nagai +12
Similar to the behavior of elementary particles, such as photons and electrons, the interference of phonon waves in artificial periodic nanostructures coherently modulates phonon b…
