· JVASP-3909· SnSb2Te4

SnSb2Te4 is a ternary chalcogenide ceramic compound composed of tin, antimony, and tellurium. This material belongs to the family of layered chalcogenides, which are of significant interest in thermoelectric and optoelectronic research due to their anisotropic crystal structure and tunable electronic properties. While primarily investigated in academic and laboratory settings, SnSb2Te4 and related compounds show promise for applications requiring materials with weak interlayer bonding and potential for mechanical exfoliation into 2D structures.
