Image of FIG. 1.
FIG. 1.

(a) Schematic illustration of a nanocomposite oxide thin film prepared by conventional self-assembled growth and SEM image of FZO-BFO nanocomposite thin films reproduced from Ref. 11 . The red squares and the blue matrix show BFO and FZO, respectively. Schematic illustrations of (b) a well-position aligned and configuration-inverted nanocomposite film and of (c) the core-shell structures.

Image of FIG. 2.
FIG. 2.

SEM images of (a) 3 μm, (b) 800 nm, (c) 300 nm, and (d) 200 nm FZO dots surrounded by BFO shells. White scale bars in each image indicate 1 μm.

Image of FIG. 3.
FIG. 3.

Cross-sectional TEM images of the (a) whole FZO core/BFO shell structure, (b) BFO shell at point “(b)” in Fig. (a), (c) FZO core grown by co-deposition at point “(c),” and (d) interface at point “(d).”

Image of FIG. 4.
FIG. 4.

Model based on the surface diffusion theory of adatoms to explain position-selective growth of BFO. (a) Schematic illustration showing a parabolic curve representing adatom spatial density C(x) following Eq. (3) . Critical nucleation threshold C 0 is independent of terrace width. (b) Terrace width L dependence of nucleation width W. The magnified images show FZO dots after the co-deposition. The yellow squares encircle the approximate nucleation area.

Image of FIG. 5.
FIG. 5.

(a) Topographic and (b) current images of the sample with 200-nm-sized FZO core/BFO shell structures.

Image of FIG. 6.
FIG. 6.

(a) PFM signal image. The inset shows topographic AFM image of a core-shell structures in 0.7 × 0.7 μm area. (b) Phase PFM image, (c) line profiles of PFM signal in the white line in (a) and (d) of phase PFM image in(b).
