superlattice

[¦sü·pər′lad·əs]
(electronics)
A structure consisting of alternating layers of two different semiconductor materials, each several nanometers thick.
(solid-state physics)
An ordered arrangement of atoms in a solid solution which forms a lattice superimposed on the normal solid solution lattice. Also known as artificial crystal; artificially layered structure; superstructure.
