WebGet a uniform phonon band structure from phonopy force constants. Parameters: structure – A structure. supercell_matrix – The supercell matrix used to generate the force constants. force_constants – The force constants in phonopy format. mesh_density – The density of the q-point mesh. WebJan 1, 2024 · The PhononUnfolding program reads parameters max_qx, max_qy and max_qz, and gets the plane wave basis. The basis functions are used to get the projection operator . From which, we finally obtain the phonon unfolding weight. The calculation results are stored in file unfold.dat, which can be plotted by using Origin or Gnuplot.
