FeCu2GeSe4
metal· JVASP-90718· FeCu2GeSe4
FeCu2GeSe4 is a quaternary iron-copper-germanium-selenium compound belonging to the chalcogenide family of semiconductors. This is an experimental research material rather than an established commercial alloy, synthesized primarily for investigating thermoelectric and optoelectronic properties in the iron-copper-germanium-selenium system. While not yet deployed in production applications, compounds in this family are of interest to researchers exploring alternatives to conventional thermoelectric materials for waste heat recovery and solid-state cooling, as well as potential semiconductor applications where the combination of elements offers tunable electronic and thermal transport properties.
