摘要: Abstract It is well known that impurities and defects in semiconductors are associated with energy levels the forbidden gap. Similar states occur at surface of a semiconductor where crystal lattice symmetry strongly disturbed. These called states. Owing to two-dimensional nature surface, their density measured per unit area, contrast bulk states, which volume. A third type similar occurs interface between two adjacent materials. Very often they also simply
