Source data for "Observation of superdiffusive phonon transport in aligned atomic chains" (https://doi.org/10.1038/s41565-021-00884-6)

Data for Fig.2 and Fig.3 of the paper "Evidences of superdiffusive phonon transport in aligned atomic chains". <br>Fig 2.(a) Measured room temperature k versus Dh. (b) Normalized room temperature k versus the normalized suspended length. (c) Measured k versus suspended length at different temperatures (30, 100 and 300 K). (d) Temperature dependence of k for different diameter wires (the suspended lengths are ~15 μm for all samples).<br>Fig 3. (a) Force-deflection curves in the bending test, together with the fitting curve. (b) Measured E versus Dh. (c) The modeled kl and the experimental data show the same trend as E increases. (d) Comparing the phonon-phonon scattering rate at different E ratio. (e) Calculated phonon mode dependent ratio of Umklapp/Normal scattering rate with E/Ebulk =1 and 6.<br>
