CaSnS3
CaSnS3 is a metastable, semiconducting ternary sulfide compound used primarily in materials research to explore complex structural phases.
About CaSnS3
CaSnS3 is a ternary sulfide compound characterized by its semiconducting electronic nature. As a metastable material, it represents an intriguing subject for solid-state chemistry research, offering unique structural configurations that deviate from more common, highly stable mineral phases. Its composition of calcium, tin, and sulfur allows for diverse atomic arrangements, which have been extensively documented across various structural databases. This extensive data availability highlights its significance in exploring non-equilibrium material states and potential functional properties. While its metastability suggests it may require specific synthesis conditions, the compound serves as a valuable model for understanding the complex phase space of metal-tin-sulfide systems. It is primarily investigated in academic and laboratory settings to expand the library of functional semiconductors.
