Enhanced intrinsic piezoelectric response in (001)-epitaxial single c-domain Pb(Zr,Ti)O3 nanorods

In this study, (001)-epitaxial tetragonal phase Pb(Zr, Ti)O3 (PZT) nanorods were fabricated on SrRuO3/SrTiO3 substrates by pulsed laser deposition. The PZT nanorods were self-assembled and grown on the substrate at an elevated oxygen pressure, and showed a complete c-domain structure. Time-resolved...

Description
Summary:In this study, (001)-epitaxial tetragonal phase Pb(Zr, Ti)O3 (PZT) nanorods were fabricated on SrRuO3/SrTiO3 substrates by pulsed laser deposition. The PZT nanorods were self-assembled and grown on the substrate at an elevated oxygen pressure, and showed a complete c-domain structure. Time-resolved x-ray diffraction measurements under an applied electric field show that the fabricated PZT nanorods exhibit a piezoelectric constant, d 33, that is significantly higher than that of thin PZT films and comparable to that for unclamped single-domain bulk crystals, which is thought to be due to a significant reduction in substrate clamping. The obtained results demonstrate that the self-assembled nanorods can achieve an enhanced intrinsic piezoelectric response, which makes them attractive for a range of practical applications.
