## Description

- description: 'The super-ballistic temperature dependence of thermal conductivity,
    facilitated by the collective phonons, has been widely studied. It has been claimed
    to be unambiguous evidence for hydrodynamic phonon transport in solids. Alternatively,
    hydrodynamic thermal conduction is predicted to be strongly dependent on the width
    of the structure as that of fluid flow, while its direct demonstration remains
    an unexplored challenge. In this work, we experimentally measured the thermal
    conductivity in several graphite wire structures with different widths from 300
    nm to 1.2 μm and studied its width dependence in a wide temperature range of 10−300
    K. We observed an enhanced width dependence of the thermal conductivity in the
    hydrodynamic window of 75 K compared to that in the ballistic limit, which provides
    indispensable evidence for phonon hydrodynamic transport from the perspective
    of the peculiar width dependence. It helps to find the missing piece to complete
    the puzzle of phonon hydrodynamics and guides future attempts for efficient heat
    dissipation in advanced electronic devices. '
