More than 35 samples of the Cu-Zn-Sn-S system were prepared along the ZnS-Cu2SnS3 section, in order to study the bulk properties of the Cu2ZnSnS4 semiconductor. During the investigation of these samples, a new quaternary phase was detected by Scanning Electron Microscopy coupled with Energy Dispersive Spectroscopy (SEM/EDS) analyses. The results indicate that the new phase has a range of solubility corresponding to Cu2-2xZn6+3xSn1-xS9 with 0 < x < 0.74 and decomposes at 790 degrees C as determined by Differential Thermal Analysis (DTA).
