· NaBiSe2

NaBiSe₂ is a ternary semiconductor compound combining sodium, bismuth, and selenium in a layered crystal structure, belonging to the family of mixed-metal chalcogenides. This is primarily a research material under investigation for next-generation optoelectronic and thermoelectric applications, with potential advantages in bandgap tuning and thermal properties compared to binary semiconductors. The material shows promise in contexts where bismuth-based compounds are valued for their spin-orbit coupling effects and environmental stability relative to lead-based alternatives.
