Mechanical reliability of monolayer MoS2 and WSe2

Mechanical reliability reflects the survival (or equivalently, failure) probability of materials under loading and is critical for their long-term and device-scale applications. So far, the mechanical reliability of two-dimensional (2D) materials remains elusive and largely unexplored, especially in long-term loading conditions. Here, through more than 300 nanomechanical experiments and 1,200 molecular dynamics simulations, we evaluate the …
