...III-V compounds such as AlN, InP, and GaAs, and II-VI compounds such as ZnS and CdTe are examples of this classification (II, III, V, and VI are groups in the periodic table). (2) Size factor compounds These include Laves phases, sigma phases, and interstitial compounds. When the radius ratio of the component atoms is close to 1.05 to 1.68, the component atoms are best packed in an AB2 type crystal with an A lattice site with 16 adjacent B sites and a B lattice site with 12 adjacent A sites. ... *Some of the terminology that mentions "size factor compound" is listed below.
