Atomic layers

Atomic layers are extremely thin sheets made up of just one or a few atoms stacked together. Think of them like a single sheet of paper or a layer of paint, but at an incredibly tiny scale. These layers can be just a few atoms thick and are studied and used in advanced technology because their unique properties differ from bulk materials. For example, a single atomic layer of graphene (carbon atoms) is incredibly strong, lightweight, and conductive, making it useful in electronics, sensors, and other innovative applications.
