Twist-assisted intrinsic toughening in two-dimensional transition metal dichalcogenides
Nature Materials, Published online: 01 April 2025; doi:10.1038/s41563-025-02193-y
Intrinsic toughening in two-dimensional transition metal dichalcogenides can be achieved simply by twisting the layers. This twisting promotes cross-layer healing and grain boundary formation, which shield fracture tips from stress concentration.
