Phonon dispersion of TiSe 2 and the colour-coded relative contribution of each phonon mode to the diffuse background, obtained for a thermal state. Here, we normalize the contributions across all nine phonon branches and the out-of-plane momentum, as illustrated in a sketch of the Brillouin zone (right). The experiment is particularly sensitive to the out-of-plane polarized acoustic branch (ZA).
