Researchers have developed a new field-based approach to analyze atomically resolved scanning transmission electron microscopy (STEM) data, representing images as spatially varying latent Bragg fields. This method provides continuous maps of crystalline order, lattice displacement, strain, and rotation, offering a more interpretable complement to traditional atom-finding techniques. The framework was applied to study Sm-substituted BiFeO3, revealing a systematic evolution of ferroelectric domains and the emergence of a period-doubled Pnma phase with increasing Sm concentration.
