Tm1 Si3

Tm₁Si₃ is a rare-earth silicon compound belonging to the family of transition metal silicides, where thulium (a lanthanide) combines with silicon in a 1:3 stoichiometry. This intermetallic compound is primarily of research interest for potential high-temperature applications and electronic device development, as rare-earth silicides exhibit unique combinations of thermal stability, electrical properties, and refractory characteristics that distinguish them from conventional silicon-based semiconductors.
