Fabrication, Characterization, Properties, and Applications of Low-Dimensional BiFeO₃ Nanostructures

Figure 4

AFM images of the epitaxial BiFeO₃ nanoislands postannealed at ((a), (b)) 650°C, ((c), (d)): 800°C, ((e), (f)): 900°C for 1 h. The left AFM images are two-dimensional ones and the right ones are the corresponding 3-dimensional ones. The insets in (a) and (c) are the enlarged AFM images of the local surface areas.
