Most of the papers in this symposium have dealt with superlattices formed from semiconductors with the diamond or zinc blende structure or derivative structures such as fluorite in which one sublattice has the diamond structure. Such superlattices are often called compositionally modulated alloys (CMA) because the two components have the same or related structures and because the two components have some mutual solubility. In these cases, depending on the differences in the lattice parameters, the resulting CMA will be almost a perfect single crystal, and the sharpness of the interfaces between the two alternating components will depend on the amount of interdiffusion during growth.
