Published: Enhanced Intrinsic Piezoelectric Response in c-domain PZT Nanorods

Our paper entitled “Enhanced Intrinsic Piezoelectric Response in (001)-epitaxial Single c-domain Pb(Zr,Ti)O3 Nanorods” has been published in Appl. Phys. Lett. The PZT nanorods were self-assembled and grown on the substrate at an elevated oxygen pressure by PLD, 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, d33, 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.
