Artificial Grain Boundaries Created by Freestanding Membrane Transfer Reveal Angle‐Dependent Ferroelectric Switching and Leakage in BaTiO 3

ABSTRACT Grain boundaries (GBs) strongly influence polycrystalline ferroelectrics, but their discrete effects are difficult to isolate because of nanoscale heterogeneity. Here, we use freestanding membrane transfer to fabricate artificial GBs with controlled, experimentally acces...
