(a) Scanning electron microscopy image of PZT perovskite nanowires. Scale bar, 50 μm. (b) High-magnification transmission electron microscopy image of PZT nanowire where nanopores and domain walls are seen. Scale bar, 50 nm. (c) Measured tetragonality (c/a) in PZT and PTO nanowires as a function of wire diameter. The error bars are the maximum of deviations in c/a values measured over 3–4 regions on given wires. The data of PTO nanowires are reconstructed from ref. 6.
