Composite Zn Cd GeAs semiconductors: structural and electrical properties.

We present the studies of structural, transport and magnetotransport properties of [Formula: see text]Cd GeAs crystals with the chemical content changing from 0 to 1. The structural studies indicate that this alloy exists as a composite two-phase material in almost the entire range of average chemical compositions. The two phase nature of our samples does have a significant influence on the carrier transport and magnetotransport of the composite alloy.
