Extract

Artificial superlattices are multilayer structures consisting of a onedimensional sequence of ultrathin layers of different semiconductors (compositional or hetero junction superlattices) or layers of the same material, modulated by periodic n- and p-doping (doping or p-n junction superlattices). The electronic properties of these new materials differ qualitatively from those of their components and can be tailored within wide limits by appropriate choice of the design parameters (i.e. superlattice period, alloy composition, and/or doping concentration). Different electronic phases (insulating, semiconducting, semimetallic, metallic, e.g.) may be obtained in this way.
