K2Bi8Se13
semiconductor· K2Bi8Se13
K2Bi8Se13 is a quaternary chalcogenide semiconductor compound combining potassium, bismuth, and selenium in a layered crystal structure. This material belongs to the family of bismuth-based selenides, which are of significant research interest for thermoelectric and optoelectronic applications due to their narrow bandgap and layered topology. While primarily a laboratory compound rather than a commercial product, K2Bi8Se13 represents the broader potential of complex chalcogenide systems for energy conversion and advanced electronics where low thermal conductivity coupled with electronic functionality is advantageous.
