Spatial dispersion in phonon focusing
The ballistic phonon flux emanating from a point–like heat source in a crystal shows strong directional dependence. This effect is called phonon focusing and is measured using a technique called phonon imaging. In situations where long wavelength phonons are involved, the observations can be expl...
