Na2Se
semiconductor· Na2Se
Na₂Se is an inorganic semiconductor compound composed of sodium and selenium, belonging to the antifluorite structure family of materials. While not widely deployed in commercial applications, it is studied in materials research for its potential in photovoltaic devices, solid-state electrolytes, and thermoelectric applications due to selenium's favorable electronic properties. Na₂Se represents an emerging class of sodium chalcogenides being investigated as alternatives to conventional semiconductors, particularly for energy conversion systems where sodium-based compounds offer potential cost and sustainability advantages over rare-earth or heavy-metal alternatives.
