- Abstract
- We demonstrate the capability of confocal Raman spectroscopy to characterize nanoscale interactions of defects with ferroelectric domain walls by identifying defect-related frequency shifts in congruent lithium niobate. These shifts resemble those observed for an external field applied anti-parallel to the ferroelectric axis, suggesting a small reduction of the electric polarization. Density functional theory calculations suggest that this reduction results from a change in the intrinsic defect cluster structure and polarization at the domain wall.
