Superlattice

A superlattice is a structure made by stacking alternating layers of two or more different materials, typically just a few nanometers thick each. This layered arrangement can create unique electronic, optical, and magnetic properties not found in the individual materials alone. Superlattices are important in advanced technologies, especially in semiconductors and nanotechnology, where they can enhance performance in devices like lasers, transistors, and solar cells. By controlling the thickness and composition of the layers, researchers can tailor the material's characteristics for specific applications.
