Direct observation of confined acoustic phonon polarization branches in free-standing semiconductor nanowires

In nanostructures, phonon confinement could lead to better control of phonon-electron coupling and thermal properties. Here, the authors use light scattering spectroscopy to measure acoustic phonons confinement in individual free-standing nanowires, their energy dispersion and energy scaling.
