Engineering nanoscale hypersonic phonon transport [PDF]

open access: yesNature Nanotechnology, 2022
Abstract Controlling the vibrations in solids is crucial to tailor their mechanical properties and their interaction with light. Thermal vibrations represent a source of noise and dephasing for many physical processes at the quantum level. One strategy to avoid these vibrations is to structure a solid such that it possesses a phononic stop band,
