The transmission characteristic of barrierless ABABA multilayer sys­tem, where A and B are materials with differing effective masses, is ana­lyzed. The system shows resonant transmission similarly to a conventional double-barrier system, but shows unique features: unity transmission at zero energy, a more structured nature of the transmission versus energy curve and a non-decreasing peak-to-valley ratio with increasing energy.
