Bi3Se4

Bi₃Se₄ is a bismuth selenide compound ceramic belonging to the chalcogenide family, characterized by layered crystal structure and semiconductor properties. This material is primarily investigated in research settings for thermoelectric and topological electronic applications, where its ability to convert thermal gradients to electrical current or exhibit unusual surface electronic states makes it attractive for next-generation energy conversion and quantum computing device architectures. While not yet widely deployed in conventional engineering, bismuth selenides represent a promising materials class for applications requiring efficient thermal-to-electric conversion or exotic electronic behavior at reduced scales.
