· CoSbS

CoSbS is a ternary semiconductor compound combining cobalt, antimony, and sulfur, belonging to the chalcogenide semiconductor family. While primarily a research material rather than a commodity product, it is investigated for potential applications in thermoelectric energy conversion and photovoltaic devices due to its tunable bandgap and mixed-metal composition. Engineers evaluating this material should consider it as an experimental candidate for next-generation energy harvesting applications where conventional semiconductors face efficiency or cost constraints.
