“…PFM method is firstly applied by Zhao et al in 2004 to measure the effective piezoelectric coefficient of ZnO nanobelt [ 36 ] and has been frequently used to investigate the piezoelectric response of LiNbO 3 NWs [ 37 ], Sb 2 S 3 NWs [ 38 ], perovskite nanofibers/NWs [ 39 , 40 , 41 ], GaN NWs [ 42 ] etc. PFM is a method based on the converse piezoelectric effect at the nanoscale which can be defined by:

where ε j is the strain, d ij is the piezoelectric coupling coefficient and E i is the applied electric field [ 43 ].…”

Due to the enhanced piezoelectric properties, excellent mechanical properties and tunable electric properties, one-dimensional (1D) piezoelectric materials have shown their promising applications in nanogenerators (NG), sensors, actuators, electronic devices etc. To present a clear view about 1D piezoelectric materials, this review mainly focuses on the characterization and optimization of the piezoelectric properties of 1D nanomaterials, including semiconducting nanowires (NWs) with wurtzite and/or zinc blend phases, perovskite NWs and 1D polymers. Specifically, the piezoelectric coefficients, performance of single NW-based NG and structure-dependent electromechanical properties of 1D nanostructured materials can be respectively investigated through piezoresponse force microscopy, atomic force microscopy and the in-situ scanning/transmission electron microcopy. Along with the introduction of the mechanism and piezoelectric properties of 1D semiconductor, perovskite materials and polymers, their performance improvement strategies are summarized from the view of microstructures, including size-effect, crystal structure, orientation and defects. Finally, the extension of 1D piezoelectric materials in field effect transistors and optoelectronic devices are simply introduced.

“…6b and S6 in the ESI †). The highest d 32 with single crystalline nature. These results reveal that the BT/CT-x/y nanocomposites own a higher piezoelectric response than a single crystalline nature, suggesting the heteroepitaxial interface in the nanocomposites plays a critical role for the enhancement of the piezoelectric property.…”

were formed via an in situ topochemical mesocrystal conversion mechanism. The density of the artificial BT/CT heteroepitaxial interface in these mesocrystalline nanocomposites can be adjusted by regulating the fraction of BT and CT in the nanocomposites. The mesocrystalline BT/CT nanocomposite with the composition close to BT/CT ¼ 1/1 presents a large piezoelectric response owing to the lattice strain derived from its heteroepitaxial interfaces with the high density in the nanocomposite.

(K0.46Na0.46La0.08)(Nb0.94Sb0.06)O3 powders were synthesized via hydrothermal method. The effects of different reaction conditions on crystal structure, micro-morphology and phase formation were analysed by XRD and SEM in detail. The results reveal that (K0.46Na0.46La0.08)(Nb0.94Sb0.06)O3 powders with orthorhombic lattice structure are synthesized at 200?C for 18 h with the total initial alkali concentration of 8mol/l. The average particle size of synthesized powders is about 500-700 nm, which has regular cubic morphology with uniform distribution. Moreover, doping with La3+ and Sb5+ inhibits the crystal growth. The phase evolution of the powders revealed that the hydrothermal synthesis of (K0.46Na0.46La0.08)(Nb0.94Sb0.06)O3 underwent two steps, where an intermediate product of K4Na4Nb6O19? 9H2O was found in the early stage at 140?C. Based on the results, the formation mechanism of (K0.46Na0.46La0.08)(Nb0.94Sb0.06)O3 powders was proposed. It can be inferred that the crystal growth model of (K0.46Na0.46La0.08)(Nb0.94Sb0.06)O3 is dissolution-crystal growth-recrystallization with the characteristics of layered growth.
