摘要：

It is shown theoretically that the recently observed spontaneous ordering of III-V alloys that yields alternate monolayer (111) superlattices provides the opportunity for achieving infrared band gaps in systems such as (InAs)1(InSb)1 and (GaSb)1(InSb)1. A substantial reduction in the direct band gap is predicted to result from the L-point folding that repel the GAMMA-band-edge states.
