Nickel Oxide (NiO) Devices and Applications: A Review

Abstract

The prospects for using nanomaterials with diameters of <100 nm in number of applications is being widely researched today across multiple domains such as biology, physics, chemistry, cosmetics, optical components, pharmaceutical drug manufacture, polymer science, mechanical engineering, and toxicology. In recent years, nanostructured materials have received steadily growing attention as a result of their peculiar and fascinating properties and applications. The electrical, optical, magnetic, thermal and mechanical properties of materials is often important when materials selection and processing decisions are being made during the design of a device. The applications of Nickel oxide (NiO) today is found in semiconductors, capacitor-inductor devices, tuned circuits, transparent heat mirrors, thermistors and varistors, batteries, micro-supercapacitors, electrochromic and chemical or temperature sensing devices. It is used in preparation of nickel cermet, plastics and textiles, in nanowires, nanofibers and specific alloy and catalyst applications. It is also used as an antiferromagnetic layers, accelerators and radar absorbing materials, aerospace and active optical filters. In this paper, current and future device applications of NiO is reviewed.
