Overview

Randomized trial investigates polarization stability in metal-ferroelectric interfaces, suggesting defect engineering as a viable method.

Key Points

  • This research aims to explore how interfacial defects influence polarization stability in ferroelectric heterostructures.
  • Utilized piezoresponse force microscopy, aberration-corrected STEM, EDS, EELS, and 4D-STEM.
  • Mapped polarization state and interfacial chemistry in a BiFeO3/La0.7Sr0.3MnO3 heterostructure.
  • Performed density functional theory calculations to assess atomic-scale mechanisms.
  • Identified a dual-charge compensation mechanism involving Sr cation diffusion and oxygen vacancy accumulation.
  • Confirmed that the strong built-in field at the interface electrostatically stabilizes polarization.
  • Demonstrated robust switchability of the polarization under repeated cycling, supporting device viability.
