The current status of HgTe–CdTe superlattices is reviewed. The properties predicted for the superlattices have been studied qualitatively in the cases where both theory and experiment exist. In particular, it has been found by both infrared absorption and photoluminescence that band gaps of the superlattices are substantially less than those of the alloy with the same average composition. Theoretical studies have concentrated on the factors (strain, band offsets, interdiffusion) that could result in substantial deviation of the properties of the superlattices from those predicted by the original simple theories. Some of the areas requiring further development are reviewed and discussed.
