  bibo_abstract:
  - The transverse thermoelectric (Nernst) effect is a powerful probe for studying
    the electronic and structural properties of materials. In this study, we employ
    transverse thermoelectric measurements to investigate the ferroelectric distortion
    in the topological crystalline insulator (TCI) Pb0.60Sn0.40Te, a compound derived
    from PbTe and SnTe, known for their exceptional thermoelectric performance and
    distinct ferroelectric properties. By leveraging Nernst measurements, we provide
    direct evidence of ferroelectric distortion in this TCI, corroborated by Shubnikov–de
    Haas quantum oscillations that confirm the presence of two topologically nontrivial
    Fermi pockets. Density functional theory calculations show that these pockets
    originate from the L and T points in the Brillouin zone of the distorted structure
    within the TCI phase. Raman spectroscopy further identifies a structural phase
    transition below 50 K, consistent with the quantum oscillation observations. This
    observation is further substantiated by temperature-dependent synchrotron X-ray
    pair distribution function analysis and transmission electron microscopy, which
    confirm the local off-centering of cations at low temperature. These findings
    underscore the potential of transverse thermoelectric measurements in unveiling
    ferroelectric distortions and their role in modulating topological quantum states,
    opening new directions for research into the synergy between ferroelectricity
    and topological phases.@eng
