Glossary

Conduction band Energy band in a crystalline solid partially filled by electrons.

Confined system A quantum system in which carriers, atoms or molecules are restricted to exist in one, two or three dimensions of the order of a few nanometers. Effective mass The mass of a particle in a crystalline solid. Gap Forbidden region for the electrons, which it is determined by the difference of energies between conduction and valence bands.

Idealized confined systems A non-real isolated quantum system whose size is of the order of few nanometers. Impurity An atom or molecule embedded in a different material.

Impurity states The additional electron levels which appears due to the presence of an impurity. MBE, MOCVD and Lithography Methods of synthesis used to the fabrication of the nanostructured materials. Nanostructure Material medium whose size is of the order of few nanometers.

Quantum dot A quantum system, in which the carriers are confined in all directions.

Quantum well A quantum system, in which the carriers are confined in only one direction, the other dimensions remain free.

Quantum well wire A quantum system, in which the carriers are confined in two directions, the other remains free. Valence band Energy band in a crystalline solid completely filled by electrons.
