Presentation Title Intrinsic and Interfacial Fatigue of Graphene

Abstract Scope With the demand for the long-term reliability of graphene devices and structures, the fatigue behavior of graphene necessitates careful investigation. Here we study the intrinsic fatigue of graphene. We discovered [1] that graphene suffers mechanical fatigue, but exhibits remarkable fatigue life of more than one billion cycles at large stress levels. Despite the record-high intrinsic fatigue life of graphene, we observed significant interfacial fatigue damage when introducing graphene-polymer contact [2]. Cyclic loading through the vdW interfaces could induce fracture of graphene even in tens of cycles, with the main fracture modes identified as in-plane shear and tear. These studies provide fundamental insights on the dynamic reliability of graphene and call for further fatigue studies of other 2D materials and their interfaces.[1] T.
