Figure 4. High-resolution TEM images near (A) BaTiO3/Pt and (B) BaTiO3/LaNiO3 interfaces in the unbuffered and buffered BaTiO3 film heterostructures, respectively. Insets are Fast-Fourier-Transformed (FFT) selected area electron diffraction (SAED) patterns of the local BaTiO3 film and its underneath LaNiO3 buffer layer.
