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结晶为一种空间群为P31c的新型三方晶系结构，其由平面硅笼目（kagome）晶格面与锂、铱晶格面交替堆叠构成。
