​Researchers detect Moiré-driven topological electronic crystals in twisted graphene 

Researchers from the University of British Columbia, the University of Washington, Johns Hopkins University and Japan’s National Institute for Materials Science have identified a new class of quantum states in a custom-engineered graphene structure. Their new study reports the discovery of topological electronic crystals in twisted bilayer–trilayer graphene, a system created by introducing a precise rotational twist between stacked two-dimensional materials.

“The starting point for this work is two flakes of graphene, which are made up of carbon atoms arranged in a honeycomb structure. The way electrons hop between the carbon atoms determines the electrical properties of the graphene, which ends up being superficially similar to more common conductors like copper,” said Prof. Joshua Folk, a member of UBC’s Physics and Astronomy Department and the Blusson Quantum Matter Institute (UBC Blusson QMI).
