Reaction pathways and optoelectronic characterization of single-phase Ag2ZnSnS4 nanoparticles
Sputtered thin films of Ag2ZnSnS4 (AZTS) have shown promising semiconducting properties in spite of the films containing SnS2, SnSx, or ZnS as impurity phases. In this study, reaction pathways were identified to ...
