· JVASP-26472· Sm3CuSiS7

Sm₃CuSiS₇ is a rare-earth metal sulfide compound containing samarium, copper, and silicon. This is a research-phase material from the family of ternary and quaternary sulfides, which are being investigated for semiconductor and photovoltaic applications due to their tunable electronic and optical properties. While not yet widely commercialized, materials in this class show promise for next-generation energy conversion devices and are of interest to researchers developing alternatives to conventional semiconductors.
