Abstract :
The new kind of semiconductor superlattice is proposed. It is based on the new type of semiconductor heterojunctions that have only carrier effective mass discontinuity and no or extremely small band lineups in both conduction and valence bands. Confinement effects in these structures are due to effective mass discontinuity only. It makes this kind of structures to be very sensitive to the boundary conditions for envelope functions. The continuity of the envelope function and its first derivative on the heteroboundary are inapplicable in this case. We estimate theoretically the band structure of this superlattice within the framework of the effective mass approximation and boundary conditions that take in to account the distinction of the Bloch functions in contacting materials
