In graphene monolayers electrons behave as if they do not have any mass, giving the material its exceptional electronic properties. In bilayer graphene, however, these qualities can be substantially altered. Until now, these effects had been controlled mainly by adjusting the “twist” between the layers. A team of researchers from Grenoble-Alpes University, INAC, and Institut Néel in conjunction with Cergy-Pontoise University showed that straining one layer more than another is a very effective way to adjust the stack’s electronic properties.
Combining strain and twist could give 2D material stacks new properties like superconductivity. Twist straintronics could very well be the next form of materials engineering!
