  bibo_abstract:
  - Lithium niobate (LNO) and lithium tantalate (LTO) see widespread use in fundamental
    research and commercial technologies reaching from electronics over classical
    optics to integrated quantum communication. The mixed crystal system lithium niobate
    tantalate (LNT) allows for the dedicate engineering of material properties by
    combining the advantages of the two parental materials LNO and LTO. Vibrational
    spectroscopies such as Raman spectroscopy or (Fourier transform) infrared (IR)
    spectroscopy are vital techniques to provide detailed insight into the material
    properties, which is central to the analysis and optimization of devices. This
    work presents a joint experimental–theoretical approach allowing to unambiguously
    assign the spectral features in the LNT material family through both Raman and
    IR spectroscopy, as well as providing an in‐depth explanation for the observed
    scattering efficiencies based on first‐principles calculations. The phononic contribution
    to the static dielectric tensor is calculated from the experimental and theoretical
    data using the generalized Lyddane–Sachs–Teller relation and compared with the
    results of the first‐principles calculations.@eng
