· Nd6 Cu2 Si2 Se14

Nd₆Cu₂Si₂Se₁₄ is a rare-earth transition-metal chalcogenide semiconductor compound combining neodymium, copper, silicon, and selenium in a layered crystal structure. This is a research-phase material studied for its potential thermoelectric and optoelectronic properties, representing an emerging class of hybrid semiconductors that leverage rare-earth elements to engineer band gaps and carrier transport. While not yet commercialized at scale, compounds in this family are investigated as candidates for solid-state cooling, waste-heat recovery, and mid-infrared photonics where the combination of rare-earth doping and chalcogenide lattices offers tunable electronic and thermal behavior.
