Superconductivity in Noncentrosymmetric Iridium Silicide Li2IrSi3

Li2IrSi3 crystallizes to a novel trigonal structure with the space group P31c, which consists of an alternate stacking of planar silicon kagome planes and Li and Ir planes. The...Li₂IrSi₃ 可结晶形成一种新型三方晶系结构，其空间群为P31c。该结构由平面状硅笼目（kagome）晶格平面与锂、铱平面交替堆叠构成。
