What is Superlattice?

A periodic structure of alternating layers of different materials, each a few nanometers thick. It shows electronic properties absent in bulk crystals and is used in lasers, buffer layers and more.

Field: Epitaxial growth

Superlattice in the explanations

A superlattice periodically stacks layers a few nm thick of different materials, such as GaAs and AlGaAs; Leo Esaki and colleagues proposed it in 1970.
