Quasi-ballistic thermal transport from nanoscale interfaces observed using ultrafast coherent soft x-ray beams

Heat dissipation from a nanoscale hot-spot is expected to be non-diffusive when a hot-spot is smaller than the phonon mean free path of the substrate. Our technique of observing diffraction of coherent soft x-ray pulses allows for very high resolution (∼pm) of thermally-induced surface distortion, a...
