Tb2 Se2
semiconductor· Tb2 Se2
Tb2Se2 is a rare-earth selenide semiconductor compound composed of terbium and selenium, belonging to the family of lanthanide chalcogenides. This material is primarily of research interest for optoelectronic and thermoelectric applications, where its narrow bandgap and layered crystal structure offer potential advantages in light emission, photodetection, and heat-to-electricity conversion. While not yet widely commercialized, Tb2Se2 and related rare-earth selenides are being investigated as alternatives to conventional semiconductors in niche applications requiring rare-earth functionality or unique electronic properties in thermally demanding environments.
