CuSe2

CuSe2 is a copper selenide compound that belongs to the family of metal chalcogenides, which combine transition metals with chalcogen elements (selenium, sulfur, tellurium). While not a mainstream engineering material in traditional structural applications, CuSe2 is primarily studied in research and emerging technology contexts for its semiconducting and optoelectronic properties, making it of interest in photovoltaic devices, thermoelectric applications, and semiconductor research where its electronic band structure and light-absorption characteristics are potentially advantageous.
