Due to the computational expense of calculating the minimum energy path, a similarly detailed analysis is not feasible for high-throughput screening applications, which relate to the ultimate goal of this work. This challenge motivated the development of a new approach to analyzing alignments. Our approach does not require DFT calculations on supercell structures, which were used to calculate the displacement fields in Gordiz et al. Instead, we considered alignments of phonon mode eigenvectors with the neighboring cation displacement field introduced in Section 2.
