摘要：

An alternative approach to synthesizing effective-mass lateral superlattices is proposed. We show theoretically that the coherency strain associated with spontaneous lateral composition modulation provides a negative feedback which results in a band-gap locking phenomenon but that the resulting longitudinal strain wave breaks the symmetry of the valence bands, thereby generating an effective-mass lateral superlattice.
