Study of Graphdiyne-based Magnetic Materials

Carbon-based magnetic semiconductors are easy to be modified with low cost and low power consumption.While they can demonstrate robust long-range magnetic ordering and show great potential for application after introducing magnetic moments.Graphdiyne(GDY),as an allotrope of carbon,exhibits intrinsic semiconductor properties and paramagnetic properties due to its unique structure and the presence of sp carbon.To improve the magnetic properties of GDY and prepare excellent magnetic semiconductor materials,scientists have done a lot of related research work.The most direct and effective method to introduce magnetism is heteroatom doping.In this review,we have entirely described the latest GDY magnetism introduction methods,effects,and theoretical calculations,etc.Doping methods include post-doping and molecular design doping.The doping elements have covered non-metallic elements(N,H,F,Cl,S),metallic elements(Fe),and functional groups.The magnetic properties of the modified GDY materials were studied by experimental analysis and theoretical calculations.This review provides a sufficient basis and direction for related researches.
