Bi₂Te₀.₀₃Se₂.₉₇ is a tellurium-selenium compound within the bismuth chalcogenide family, a class of narrow-bandgap semiconductors commonly studied for thermoelectric and optoelectronic applications. This specific composition represents a selenium-rich variant of bismuth telluride with minor tellurium substitution, tuning the electronic and thermal transport properties relative to the well-established Bi₂Te₃ and Bi₂Se₃ end members. The material is primarily of research interest for optimizing thermoelectric efficiency in power generation and cooling modules, and may see application in infrared detectors and narrow-gap photovoltaic devices where the bandgap engineering provided by tellurium doping is exploited.
