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.
[3] The binary compounds in this system form a wide range of solid solutions.
The IIV2 compounds exhibit wide solid solution ranges with CdP4 even though the stoichiometry and structures of the components differ.
Zinc phosphide is a semiconductor material with a direct band gap of 1.5 eV[10] used in photovoltaics.
