SLD (Surface Layer Density)

Surface Layer Density (SLD) is a measure of how densely packed the atoms or molecules are in the outermost layer of a material. It indicates the amount of mass (or atoms) per unit area on the surface, which can influence properties like adhesion, corrosion resistance, and chemical reactivity. Essentially, SLD helps scientists understand how tightly packed the surface is, affecting how the material interacts with its environment. It is useful in fields like materials science and surface engineering to tailor surfaces for specific applications.
