## Description

- description: A compressive strength limit is one of critical parameters for thermoelectric
    materials. In this study, we synthesized a single crystal of Yb-filled Co–Sb-based
    skutterudite. We assessed the compressive pressure dependence of internal strain
    using high-resolution synchrotron radiation X-rays at SPring-8. The prepared single
    crystal was identified as Yb0.148Co4Sb12.54, with a lattice parameter of 9.0504
    Å. Compressive testing was performed until the sample fractured, revealing a compressive
    strength limit of 591.3 MPa. The stress–strain curve exhibited a nearly constant
    slope for strains exceeding 0.07%, leading to an estimated Young’s modulus of
    154.6 GPa.
