To acces final work see “Confined crack propagation in MoS2monolayers by creating atomic vacancies”, ACS Nano 15.1 (2021): 1210-1216, 10.1021/acsnano.0c08235” In two-dimensional crystals, fractures propagate easily, thus restricting their mechanical reliability. This work demonstrates that controlled defect creation constitutes an effective approach to avoid catastrophic failure in MoS2 monolayers. A systematic study of fracture mechanics in MoS2 monolayers as a function of the density of atomic vacancies, created by ion irradiation, is reported. Pristine and irradiated materials were studied by atomic force microscopy, high-resolution scanning transmission electron microscopy, and Raman spectroscopy. By inducing ruptures through nanoindentations, we determine the strength and length of the propagated cracks within MoS2 atom-thick membranes as a function of the density and type of the atomic vacancies. We find that a 0.15% atomic vacancy induces a decrease of 40% in strength with respect to that of pristine samples. In contrast, while tear holes in pristine 2D membranes span several microns, they are restricted to a few nanometers in the presence of atomic and nanometer-sized vacancies, thus increasing the material's fracture toughness Financial support is acknowledged from PID2019-106268GB-C31, S2018/NMT-451, FLAG-ERA JTC2017, Ramon Areces Foundation, and JdC Fellowship FJCI-2017-32370 American Chemical Society http://hdl.handle.net/10486/710501 https://dx.doi.org/10.1021/acsnano.0c08235 |
