= Superstructure (condensed matter)
{wiki=Superstructure_(condensed_matter)}
In the context of condensed matter physics, a "superstructure" refers to a periodic arrangement of atoms or molecules that goes beyond the basic repeating unit of a crystal lattice. This term is commonly used to describe phenomena where the atomic arrangement exhibits a longer-range periodicity, often resulting from certain interactions within the material, such as those related to changes in composition, temperature, or pressure.
