## Description

- description: The Tesla valve benefits the rectification of fluid flow in microfluidic
    systems1–6 and inspires researchers to design modern solid-state electronic and
    thermal rectifiers referring to fluid-rectification mechanisms in a liquid-state
    context. In contrast to the rectification of fluids in microfluidic channels,
    the rectification of thermal phonons in micro-solid channels presents increased
    complexity owing to the lack of momentum- conserving collisions between phonons
    and the infrequent occurrence of liquid-like phonon flows. Recently, investigations
    and revelations of phonon hydrodynamics in graphitic materials7–10 have opened
    up new avenues for achieving thermal rectification. Here we demonstrate a phonon
    hydrodynamics approach to realize the rectification of heat conduction in isotopically
    enriched graphite crystals. We design a micrometre- scale Tesla valve within 90-nm-thick
    graphite and experimentally observe a discernible 15.2% difference in thermal
    conductivity between opposite directions at 45 K. This work marks an important
    step towards using collective phonon behaviour for thermal management in microscale
    and nanoscale electronic devices, paving the way for thermal rectification in
    solids.
