Ferroelectric polarization mapping through pseudosymmetry-sensitive EBSD reindexing
The research developed a new Electron Backscatter Diffraction (EBSD) reindexing technique to accurately map local ferroelectric polarization directions in polycrystalline materials like BTO and PZT, which are challenging due to close crystallographic pseudosymmetries. This method uses a Pseudosymmetry Confidence Index (CIPS) that outperforms traditional metrics, enabling reliable domain identification.
