主　　题：network interlayer structure 

摘      要：Kagome lattice,characterized by two-dimensional honeycomb network of corner-sharing triangles[1],presents flat bands,Dirac cones,and van Hove singularities(VHSs),which have been theoretically predicted and experimentally observed[2-4].When combined with spin-orbit coupling(SOC)and magnetism,novel properties have *** kagome materials vary,most of their strong interlayer interactions make the synthesized crystals not layered,and the properties deviating from the raw two-dimensional kagome *** crystals are difficult to fabricate into thin devices and to tune the physical properties of the materials using gate voltage.
