Metastable (InP)1−xGe2xalloys as potential materials with band gap ≂10 μm

Based on the idea of a zincblende‐diamond structural phase transition, we predict that metastable, crystalline, substitutional alloys of (InP)1−xGe2x should exhibit significantly smaller fundamental band gaps than has been expected for random alloys of InP and Ge, and hence may be candidates for materials with gaps ≂10 μm.
