· JVASP-45256· CoPSe

CoPSe is a cobalt-based selenide compound, representing an intermetallic or ceramic-like material in the cobalt-selenium system. This is primarily a research material investigated for its potential in thermoelectric, catalytic, and energy storage applications, rather than an established engineering structural material. Its layered crystal structure and electronic properties make it of interest in materials science for next-generation devices requiring efficient charge or heat transfer.
