· JVASP-92324· Ca3SbP

Ca₃SbP is an intermetallic ceramic compound composed of calcium, antimony, and phosphorus, belonging to the family of ternary phosphide ceramics. This material is primarily of research interest for semiconductor and optoelectronic applications, where its electronic band structure and thermal properties are being investigated for potential use in solid-state devices. While not yet widely commercialized, compounds in this material class show promise for next-generation photovoltaics, thermoelectrics, and wide-bandgap semiconductor applications where alternatives like conventional III-V semiconductors or oxide ceramics may have limitations.
