Bilayer Graphene Works as an Insulator

A research team led by physicists at the University of California, Riverside has identified a property of “bilayer graphene” (BLG) that the researchers say is analogous to finding the Higgs boson in particle physics.

Graphene, nature’s thinnest , is a one-atom thick sheet of arranged in a . Because of graphene’s planar and chicken wire-like structure, sheets of it lend themselves well to stacking.

BLG is formed when two graphene sheets are stacked in a special manner. Like graphene, BLG has high current-carrying capacity, also known as high electron . The high current-carrying capacity results from the extremely high velocities that electrons can acquire in a .
