主　　题：Graphene,crack detection inductance electromagnetic induction insensitive to doping 

摘      要：Detection of cracks is a great concern in production and operation processes of graphene based devices to ensure uniform ***,we show a detection method for graphene cracks by electromagnetic *** time varying magnetic field leads to induced voltage signals on graphene,and the signals are detected by a *** measured level of induced voltage is correlated with the number of cracks in graphene *** correlation is attributed to the increasing inductive characteristic of defective graphene,and it is verified by electromagnetic simulation and radio frequency ***,we demonstrate that the induced voltage signal is insensitive to the doping level of *** work can potentially lead to the development of a high-throughput and reliable crack inspection technique for mass production of graphene applications.
