Abstract
Heterojunctions are formed from two adjoining semiconductor crystals with different bandgap energies. One distinguishes junctions of the same conduction type (n-n, p-p) from junctions of different type (p-n). In the ideal case we have an abrupt junction between the materials. In practice junctions may occur within a few (2 or 3) atomic layers. With lattice mismatching (> 0.1%) of the two semiconductors defects are formed at the interface, which lead to considerable deviations from the ideal behavior of a heterojunction.
