ceramic

· JVASP-51261· TlBTe2

TlBTe2 is a ternary semiconductor ceramic compound composed of thallium, boron, and tellurium elements. This material belongs to the family of chalcogenide semiconductors and is primarily investigated in research contexts for its electronic and optical properties. TlBTe2 and related thallium-based tellurides are of interest in thermoelectric applications, infrared optics, and solid-state physics research, where the heavy thallium element and telluride bonding can enable favorable band structures and carrier transport; however, the material remains largely experimental with limited industrial deployment due to toxicity concerns associated with thallium and the challenge of synthesis and processing.
