ceramic

· JVASP-106749· SbTe

SbTe is an intermetallic ceramic compound composed of antimony and tellurium, belonging to the chalcogenide ceramic family. It is primarily investigated for thermoelectric applications where the conversion between thermal and electrical energy is critical, leveraging the wide bandgap and carrier mobility typical of Sb-Te systems. The material is notable in phase-change memory devices and thermal management applications, where its ability to reversibly switch between crystalline and amorphous states (characteristic of the Sb-Te family) makes it valuable for data storage and heat dissipation in advanced electronics.
