· Ho2 Sb6

Ho₂Sb₆ is a rare-earth antimony compound belonging to the family of skutterudite-related semiconductors, composed of holmium and antimony in a 1:3 stoichiometric ratio. This material is primarily of research interest for thermoelectric applications, where its crystal structure and electronic properties are being investigated for potential use in waste heat recovery and solid-state cooling devices. Ho₂Sb₆ represents an experimental compound rather than an established engineering material, but it exemplifies the broader class of rare-earth pnictide semiconductors being explored to improve thermoelectric efficiency and compete with conventional Bi₂Te₃-based systems.
