Long Ju, the lead researcher, describes the new material, rhombohedral pentalayer graphene, as a gold mine, with discoveries revealed at every step.

A novel class of quantum particles behaves in unexpected ways

Rhombohedral pentalayer graphene is a unique form of pencil lead. Pencil lead, or graphite, consists of graphene, a single layer of carbon atoms arranged in a hexagonal pattern. Rhombohedral pentalayer graphene has five layers of graphene stacked in a specific order.
