“…The scanning measurements confirmed that the orientation and alignment of the nanowires were controlled by the surface texture of the substrate and the roughness of the deposited film seed layers, respectively. According to some studies [ 17 , 18 , 19 ], the thickness and roughness of the seed layers have a greater impact on the alignment of the nanorods than the texture of the substrate. AFM micrographs have been developed in the field of nanotechnology for various applications [ 20 , 21 , 22 , 23 , 24 ].…”

Zinc oxide (ZnO) nanorods have attracted considerable attention in recent years owing to their piezoelectric properties and potential applications in energy harvesting, sensing, and nanogenerators. Piezoelectric energy harvesting-based nanogenerators have emerged as promising new devices capable of converting mechanical energy into electric energy via nanoscale characterizations such as piezoresponse force microscopy (PFM). This technique was used to study the piezoresponse generated when an electric field was applied to the nanorods using a PFM probe. However, this work focuses on intensive studies that have been reported on the synthesis of ZnO nanostructures with controlled morphologies and their subsequent influence on piezoelectric nanogenerators. It is important to note that the diatomic nature of zinc oxide as a potential solid semiconductor and its electromechanical influence are the two main phenomena that drive the mechanism of any piezoelectric device. The results of our findings confirm that the performance of piezoelectric devices can be significantly improved by controlling the morphology and initial growth conditions of ZnO nanorods, particularly in terms of the magnitude of the piezoelectric coefficient factor (d33). Moreover, from this review, a proposed facile synthesis of ZnO nanorods, suitably produced to improve coupling and switchable polarization in piezoelectric devices, has been reported.

In this work, zinc oxide (ZnO) thin films on quartz substrates were fabricated using the spin-coating method. Thermal annealings from 350 • C to 1050 • C have been performed in 50 • C increments and for two annealing durations (0.5 h and 8 h). X-ray diffraction (XRD) spectra, scanning electron microscopy micrographs, and UV-Vis absorption spectra of all the samples have been elucidated from mechanical and optical points of view. It has been observed that for all annealing temperatures, the crystal phase has been obtained. After 850 • C annealings, a new crystal phase related to Zn 2 SiO 4 (willemite) has also been appeared in XRD spectra. This phase remained stable up to 1050 • C annealing together with the ZnO crystal phase. It has been found that the nano/micro rod diameters of the ZnO crystals reach to a maximum (0.4 μm) at the 700 • C annealing for both annealing durations. For 650 • C annealings, ZnO nanorods appeared to be split into two homogeneous nanorods of length of 500 μm and of width of 0.35 μm (350 nm) which was not the case for all other annealing temperatures. After 950 • C annealings, ZnO nano/micro rods started to disappear and formed homogeneous ZnO thin films.
