Synthesis and X-ray Diffraction Studies of Cu2ZnGexSn1 – xSe4 Solid Solutions

Abstract

Quaternary compounds (Cu₂ZnGeSe₄ and Cu₂ZnSnSe₄) and solid solutions on their basis are prepared via single-temperature synthesis from Cu, Zn, Ge, Sn, and Se. The crystallographic characteristics of the synthesized compounds and Cu₂ZnGe_xSn_1 – xSe₄ solid solutions are determined using the X-ray diffraction method at room temperature. It is found that parameters a and c reduce with increasing Ge concentration.
