Description
Nickel (Ni) single crystal substrates are precision-engineered materials with a well-defined crystallographic orientation. Thanks to their excellent mechanical strength, corrosion resistance, high thermal stability, and magnetic properties, Ni single crystals are widely used for thin film deposition, catalysis studies, magnetic thin film research, and surface science investigations. Nickel substrates serve as essential platforms for the epitaxial growth of metallic and oxide films, helping researchers to understand fundamental surface phenomena and material behaviors at the atomic level.
