BaSe
semiconductor· BaSe
Barium selenide (BaSe) is an inorganic semiconductor compound belonging to the II–VI semiconductor family, characterized by a rock salt crystal structure with moderate mechanical stiffness. While not widely deployed in high-volume production, BaSe is studied primarily in research contexts for infrared optics, photodetection, and thermoelectric applications where its bandgap and thermal properties offer potential advantages over more conventional semiconductors like CdTe or PbS. Engineers consider BaSe when designing infrared imaging systems or specialized optoelectronic devices that require materials with specific refractive index and absorption characteristics in the mid-to-far infrared spectrum.
