摘要：

The energy-band spectrum of a Si/Ge strained multivalley superlattice structure is investigated within an antibonding orbital model. It is shown that the energy-band spectrum as a function of the well-width exhibits a pairing interference pattern due to inter-valley mixing effect. We found two interesting interference effects: In each pair, not only (1) the energy separation between the two bands but also (2) the two band-widths are oscillatory functions of the width of the well material.
