Ribbons of graphene, rather than squares, could make a better platform for probing the unusual electronic effects that arise from twisting and straining adjacent layers of two-dimensional (2D) materials. This is the finding of scientists in the US, Denmark, France and Japan, whose approach differs significantly from previous “twistronics” studies that focused on twisting two flakes of material with respect to each other and then stacking them. According to the team, the new ribbon-based technique could give researchers better control over the twist angle, making the electronic effects easier to study.
