Abstract The Energy band edges of type-II InAs/GaSb (001) misaligned superlattices as functions of InAs and GaSb layer thicknesses are calculated by a pseudopotential method with quick convergency. The results show the trend of deep-shallow transitions of impurities in the superlattices. The regime in which the superlattice changes from semiconductor to semimetal is also showed.
