Intrinsic toughening and stable crack propagation in hexagonal boron nitride

If a bulk material can withstand a high load without any irreversible damage (such as plastic deformation), it is usually brittle and can fail catastrophically 1 , 2 . This trade-off between strength and fracture toughness also extends into two-dimensional materials space 3 – 5 . For example, graphe...
