Paper Abstract

The term `semiconductor superlattice' is usually used to refer to a periodic structure of thin layers of two semiconductors along one dimension. The period in thickness lies typically in the range from several to tens of nanometers, which is shorter than the electron mean free path in semiconductors but longer than the crystal lattice constant. This periodic, or superlattice potential, modifies significantly the band structure of the host semiconductors, creating minizones in wave-vector space and subbands in energy. In this regard the superlattice can be considered as a new synthesized semiconductor not present in nature, which exhibits unusual electronic and optical properties. The paper presents the fundamentals of the physics of semiconductor superlattices, as well as the crystallization methods and the most interesting application areas of these man-made structures.
