For the past 15 years, physicists have been fascinated by twisted bilayer graphene, a structure formed by stacking two sheets of graphene and rotating one relative to the other. Depending on the twist angle, this material can exhibit magnetism, superconductivity, and various other electronic phenomena (see Trend: Bilayer Graphene’s Wicked, Twisted Road). Now Zhe Wang at Xi’an Jiaotong University in China and his colleagues have demonstrated an alternative way to adjust the electronics of bilayer graphene [1]. Their technique involves sliding one sheet over the other without rotation and could be applied to a wide range of 2D material systems.
