Zinc cadmium phosphide arsenide
Semiconductor material
Zinc cadmium phosphide arsenide (Zn-Cd-P-As) is a quaternary system of group II (IUPAC group 12) and group V (IUPAC group 15) elements. Many of the inorganic compounds in the system are II-V semiconductor materials. The quaternary system of II3V2 compounds, (Zn1−xCdx)3(P1−yAsy)2, has been shown to allow solid solution continuously over the whole compositional range.[1] This material system and its subsets have applications in electronics, optoelectronics, including photovoltaics, and thermoelectrics.[2]

Quaternary compounds
The compounds of the form II3V2 have similar crystalline structures and exhibit full solid solution over the whole compositional range. The compounds of the form II-V2 allow only partial solid solution.[3]
Ternary compounds
The binary compounds in this system form a wide range of solid solutions. This miscibility reflects the close similarity of the structures of the binary phases. The IIV2 compounds exhibit wide solid solution ranges with CdP4 even though the stoichiometry and structures of the components differ.[3]
The optoelectronic and band properties of some ternary compounds have also been studied. For example, the bandgap of Zn3(P1−yAsy)2 solid solutions is direct and tunable from 1.0 eV to 1.5 eV. This solubility enables the fabrication of tunable nanowire photodetectors.[8] The solid solution (Zn1−xCdx)3As2 exhibit a topological phase transition at x ~ 0.62.[9]
