We proposed the mathematical model for the collective dynamics of charge in a semiconductor heterostructure which presents itself as a chain of semiconductor superlattices divided by heavy doped regions. Using the developed model we considered this structure operated in a mode characterized by the reinjection of charge domains from one superlattice to another.
