Bi2Se

Bi₂Se is a bismuth selenide compound and a layered chalcogenide ceramic with significant interest as a topological insulator material. It is primarily investigated in research and emerging technology contexts rather than conventional engineering applications, where its unique electronic properties—particularly surface conduction with topologically protected states—make it valuable for fundamental physics studies and next-generation quantum devices. Engineers and physicists consider Bi₂Se for applications where conventional semiconductors are inadequate, leveraging its distinctive band structure to enable new functionality in electronic, thermal, and spintronic systems.
