A short, elementary introduction into the physics of n-i-p-i doping superlattices is presented. Their electrical and optical properties which result from the unique tunability of their bandstructures are discussed. Examples of GaAs based n-i-p-i and hetero-n-i-p-i superlattices illustrate the novel phenomena that have been predicted and experimentally observed. The device potential of these engineered semiconductor materials is also discussed.
