Overview

Research highlights programmable polarization changes in ferroelectric membranes, suggesting new avenues for electronic applications.

Key Points

  • This work aims to explore methods for engineering ferroelectric polarization through controlled bending strain in membranes.
  • Employed a photosensitive-polymer patterning technique to create bending strain profiles in ferroelectric membranes.
  • Utilized BaTiO3 as a model system to investigate polarization responses.
  • Induced 90° polarization rotation and 180° polarization reversal via engineered strain gradients.
  • Demonstrated successful programmable bending in ferroelectric membranes.
  • Achieved deterministic 90° rotation of polarization through controlled strain.
  • Observed 180° polarization reversal due to flexoelectric coupling.
