The initial crystal structure used to perform phonon calculation is
obtained from `the Materials Project`_. The phonon band structure
paths are determined using `SeeK-path`_. More details about how to
obtain the crystal structure, how to determine the band structure
paths, and those citations are found at
:ref:`crystal_structure_and_citation`.
