superlattice

Such materials, known as superlattices, have a repeated structure of n layers of GaAs, m layers of AlAs, n layers of GaAs, m layers of AlAs, and so forth. Superlattices represent artificially created structures that are thermodynamically stable; they have many applications in the modern electronics industry. Another lattice-matched…

Superlattices are periodic structures of repeating wells that set up a new set of selection rules which affect the conditions for charges to flow through the structure. Superlattices have been exploited in cascade lasers to achieve far infrared wavelengths. Modern telecommunications is based on semiconductor…

…lattice spacings of crystals, “superlattices” consisting of alternating layers of atoms with high and low atomic numbers can be made to reflect the softer X-rays. It is possible to construct these materials where each layer thickness (a layer may consist of hundreds of atoms to a single atom) can…
