· Gd6Ge2.5S14

Gd6Ge2.5S14 is a rare-earth chalcogenide semiconductor compound combining gadolinium, germanium, and sulfur in a layered crystal structure. This material belongs to the family of rare-earth germanium sulfides, which are primarily of scientific and research interest rather than established commercial production. The compound is investigated for potential applications in solid-state thermoelectric devices, thermal management systems, and advanced optoelectronic materials, where its unique phonon scattering properties and band structure could offer advantages over conventional semiconductors in specialized high-temperature or energy-conversion contexts.
