- Abstract
Highly organised arrangements of vertically aligned nanostructures are crucial foundational elements in creating versatile devices. Vertically aligned ZnO nanorods (NRs) offer many remarkable applications in electronics, optoelectronics, and electromechanical nanodevices. This review examines recent advancements in synthesising arrays of ZnO nanorods. This manuscript explores the significance of vertically aligned ZnO nanorods in creating versatile devices. It discusses the properties of vertical ZnO nanorods, including their high aspect ratio, large surface area, tunable optical properties, piezoelectricity, chemical stability, and biocompatibility. Recent methods for synthesising vertically aligned ZnO nanorods are detailed, such as using colloidal lithography and a sol-gel-prepared ZnO seed layer. Various studies highlight the controlled growth of ZnO nanorods through top-down fabrication approaches like nanoimprint lithography, electron beam lithography, colloidal lithography, and laser interference lithography, followed by hydrothermal methods. It also includes nanostructure growth using a nanoporous polycarbonate template via electrodeposition. These nanofabrication techniques offer simplicity, uniformity across large wafer-scale areas, and the ability to precisely control the growth of vertical ZnO nanorods, which holds potential for the fabrication of high-performance devices. The last chapter highlights various potential applications of vertically aligned ZnO nanorods, including energy conversion, optoelectronics, sensors, bio-medics, and environmental remediation.
