Abstract
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 MoSe crystals and measures their fracture strength for the first time.
摘要
开发了一种原位定量拉伸测试平台，以实现扫描电子显微镜内二维材料的自由站立膜的平面内均匀加载。原位拉伸测试首次揭示了大面积 MoSe 晶体的脆性断裂，并测量了它们的断裂强度。
