Phonons in Slow Motion: Dispersion Relations in Ultra-Thin Si Membranes
John Cuffe, Emigdio Chavez, Andrey Shchepetov +11
We report the changes in dispersion relations of hypersonic acoustic phonons in free-standing silicon membranes as thin as \sim 8 nm. We observe a reduction of the phase and group…
