Cu5Sn2Se7
metal· JVASP-119567· Cu5Sn2Se7
Cu5Sn2Se7 is a quaternary copper-tin-selenium compound that belongs to the family of chalcogenide semiconductors and intermetallic materials. This is a research-phase material primarily studied for its potential in thermoelectric, optoelectronic, and photovoltaic applications due to the semiconductor properties arising from its mixed-metal composition and chalcogenide framework. The material represents an emerging alternative for energy conversion and light-harvesting devices where the combination of copper, tin, and selenium offers tunable electronic properties and thermal management capabilities distinct from conventional binary or ternary semiconductors.
