“…On a patterned substrate, the growth rate of the nanowires was shown to be inversely proportional to the nanowire density [267,268], simply because the growth nutrient was shared between the competing nanowires. Also, the as-grown nanowires were not straight or uniformly oriented on seeded substrate [77], even though well-controlled ZnO nanowire arrays were grown on GaN substrates using photolithography with one or two nanowires growing out of one spot [269].…”

One-dimensional (1D) ZnO nanostructures have been studied intensively and extensively over the last decade not only for their remarkable chemical and physical properties, but also for their current and future diverse technological applications. This article gives a comprehensive overview of the progress that has been made within the context of 1D ZnO nanostructures synthesized via wet chemical methods. We will cover the synthetic methodologies and corresponding growth mechanisms, different structures, doping and alloying, positioncontrolled growth on substrates, and finally, their functional properties as catalysts, hydrophobic surfaces, sensors, and in nanoelectronic, optical, optoelectronic, and energy harvesting devices.

Morphology-rich ZnO as a direct band gap II−VI semiconductor is a promising material for photonic, optical, and electronic devices. Nanostructured materials have provided a leading edge to the next-generation technology due to their distinguished performances and efficiencies for device fabrication. The nonlinear optical (NLO) properties and mechanisms dependent on the size and dimensionality of ZnO nanostructures remain to be elucidated. Herein, we begin to provide a comprehensive summary of the status of research activities in ZnO nanostructures, including their syntheses and potential applications, with an emphasis on multidimensional ZnO nanostructure based growth, properties, and applications. Density functional theory calculations confirmed the effect of ZnO size, morphology, and defect on the structure, work function, and charge density distribution of the electron band. Finite difference time domain simulation confirmed that the electric field, magnetic field, and Poynting vector of the ZnO system with the morphology changes were applied. Moreover, the ultrafast NLO and carrier dynamics of feature-rich ZnO nanostructures were studied. The effects of different experimental parameters on the morphology and linear and nonlinear excitation and radiation mechanisms of ZnO nanostructures were studied by constructing an electron transfer mechanism diagram and the Z-scan technique. The results show that the properties and properties of ZnO nanostructures can be regulated and controlled by the structure and morphology. The application and performance of feature-rich zinc oxide nanostructures in photoelectric functional devices are prospected, which will provide valuable references and guidance for related researchers.
