KAuSe2
metal· KAuSe2
KAuSe2 is an intermetallic compound combining potassium, gold, and selenium, representing a layered ternary material that is not currently established in conventional engineering practice. This compound is primarily of research interest in materials science, particularly for applications exploring two-dimensional materials and layered crystal structures; the relatively low exfoliation energy suggests potential for mechanical exfoliation into thin layers, making it a candidate material for investigations into nanoelectronics, optoelectronics, or heterostructure devices where novel electronic properties of few-layer systems are being explored.
