This work was mainly supported by JST-PRESTO “Nanosystems and Emergent Functions” and “Scientific Innovation for Energy Harvesting Technology, Grant No. JPMJPR16R9,” and partially supported by the JSPS KAKENHI Grant Nos. 26709047 (T.Y.), 15K13944 (T.Y.), 19J21955 (K.O.), 19H02421 (T.K.), and 19H04531 (T.K.). The synchrotron radiation experiments were performed at the BL13XU and BL15XU beamlines at SPring-8 with the approval of the Japan Synchrotron Radiation Research Institute (JASRI) (Proposal Nos. 2011A1550, 2012A1491, and 2016B1543) and the Synchrotron x-ray Station, NIMS (Proposal Nos. 2014A4908, 2014B4908, and 2018A4901). The authors are grateful to Dr. K. Yokoyama, Dr. S. Takeda, Professor Y. Kagoshima, and Professor J. Matsui, University of Hyogo, for their technical contribution in the BL15XU measurement. The TEM experiments were supported by Tohoku University Nanotechnology Platform Project sponsored by MEXT and the Collaborative Research Project of Laboratory for Materials and Structures, Institute of Innovative Research (11M196).

N2 - 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.
