Growth, crystal structure, and properties of Cu2Zn1-xCdxSnS4 solid solutions

Abstract

The phase diagram of the Cu 2 CdSnS 4 –Cu 2 ZnSnS 4 system was constructed using data on differential thermal, X-ray phase and microstructure analysis methods. The diagram can be attributed to the first type according to the Rosebohm classification. The Cu 2 CdSnS 4 –Cu 2 ZnSnS 4 solid solution single crystals were grown by chemical vapor transport using iodine as a transport agent. Their structure and unit cell parameters as well as compositional dependences of lattice parameters, pycnometric, X-ray densities and microhardness were determined. It was found that the Vegard's law is fulfilled in solutions studied.
