Overview

This research reveals hysteretic polarization in BaTiO3 films on Nb-doped SrTiO3, highlighting MBE's utility.

Key Points

  • Hysteretic polarization was observed with a remnant polarization of ∼15 μC cm–2 in BaTiO3 films.
  • The Positive-Up-Negative-Down method effectively isolated intrinsic ferroelectric responses from other contributions.
  • Defect-engineered BaTiO3 heterostructures may offer new applications in electronics and spintronics.
  • The asymmetry in switching behavior suggests potential impacts from structural defects in the films.
