Abstract: Chalcopyrite compounds such as ZnSnAs2 or CuInTe2 can all be viewed as derivative compounds of zinc blende, 1 see Fig. 1. In a zinc-blende compound such as GaAs, the Ga and As atoms each independently occupy one set of face-centered cubic (fcc) positions, see Fig. 1(a). In a chalcopyrite compound such as ZnSnAs2 [see Fig. 1(b)], As atoms occupy one set of fcc positions and Zn and Sn the other. For this example, the cations originate from columns II and IV of the Periodic Table and the average valence of the pair (ZnSn) is III. Chalcopyrite (C) is an example of an average-valence compound and has a space \(I\bar 42d\) group that is a subgroup of the zinc-blende (Z) space group \(F\bar 43m\). Similarly, there exist chalcopyrite compounds derived from II-VI compounds, e.g., CuInTe2.
