Annotation: The article is devoted to semiconductors with low-dimensional systems, which are actively developing and are a relatively new direction. The concept of quantum wells, quantum threads, and quantum dots is revealed in the paper. The concept of Quantum States is important for active device technology, for example the behavior Quantum well lasers, Photo detectors, Resonant Tunneling Diodes etc. can be explained by means of this concept.

Keywords: Molecular beam epitaxy, Quantum wells, effective mass, potential well, Schrodinger equation, finite barrier.
