Brittle Fracture of 2D MoSe2.
An in situ quantitative tensile testing platform is developed to enable the uniform in-plane loading of a freestanding membrane of 2D materials inside a scanning electron microscope. The in situ tensile testing reveals the brittle fracture of large-area MoSe2crystals and measures their fracture strength for the first time.
