The team virtually examined this exotic phase transition in graphene boron nitride molybdenum disulfide and graphane all promising monolayer materials.
Within the honeycomb-like lattices of monolayers like graphene boron nitride and graphane the atoms rapidly vibrate in place.
In the case of graphene boron nitride and graphane the backbone of the perfect crystalline lattice distorted toward isolated hexagonal rings.
The soft mode distortion ended up breaking graphene boron nitride and molybdenum disulfide. As the monolayers were strained the energetic cost of changing the bond lengths became significantly weaker in other words under enough stress the emergent soft mode encourages the atoms to rearrange themselves into unstable configurations.
Tunable hybrid polaritons realized with graphene layer on hexagonal boron nitride Abstract: Physicists have found a way to control the length
Infrared light can also launch polaritons within a different type of two-dimensional crystal called hexagonal boron nitride.
"Our structures are made from the new wonder material graphene and its cousin boron nitride, which endow them with several advantages compared to traditional metal-based metamaterials.
