Bi₁.₉₈Te₃Sb₀.₀₂ is a doped bismuth telluride compound, a member of the V–VI narrow-bandgap semiconductor family widely studied for thermoelectric applications. This antimony-doped variant is engineered to optimize charge carrier concentration and phonon scattering, making it relevant for solid-state heat pumping, power generation from waste heat, and temperature sensing in demanding thermal environments. Bismuth telluride remains the benchmark thermoelectric material for near-room-temperature operation, and dopant tuning—as seen here with Sb substitution—is a standard approach in industry to improve the figure of merit and thermal stability compared to unmodified Bi₂Te₃.
