FIG. 1.

(a) XRD pattern of the as-synthesized nanowires powder. (b) SEM image of an isolated BiFeO3 nanowire lying on Pt/Si substrate. (c) TEM image of a typical BiFeO3 nanowire with (d) a SAED pattern obtained from the same wire.

FIG. 2.

(a) Schematic illustration of the experimental setup for PFM study of the BiFeO3 nanowire. (b) Three-dimensional AFM topographic image representation of an individual nanowire lying on Pt coated silicon substrate surface. The inset shows the corresponding scanline taken along the solid white line crossing the NW.

Image of FIG. 3.
FIG. 3.

(a)-(c) x and z-PFM hysteresis loops taken from the nanowires shown in each figure, respectively. (d) Schematic diagram showing the relative geometry position between [111]c direction in the nanowires and the substrate.

Image of FIG. 4.
FIG. 4.

Calculated piezoelectric surface for the longitudinal piezoresponse d zz (a) and lateral piezoresponse d zxz (b). (c) Cross-section of (b) in the plane, containing the spontaneous polarization.
