Columbia researchers recently published work using quantum mechanics and a supercomputer to reveal how the world’s strongest, thinnest materials break. The study was inspired by previous work on graphene and found that several other monolayer materials have a very similar failure mechanism despite having extremely different electronic properties.

Their results contradict previous explanations of why graphene breaks based on a well-known concept in physics called a “Peierls instability”.

The C, B, N, H, Mo, and S atoms are represented as brown, green, silver, white, purple, and yellow spheres, respectively. Dashed lines indicate the undistorted strained lattice.
