Stacking three layers of graphene with a twist speeds up electrochemical reactions

Researchers from the University of Michigan, the U.S. Department of Energy’s SLAC National Accelerator Laboratory, Carnegie Mellon University, and Harvard University have discovered that the electrical conductivity of three layers of graphene, in a twisted stack, is similar to that of “magic angle” bilayer graphene. Stacking three layers of graphene introduced an additional twist angle, creating non-repeating patterns, at small-angle twists – unlike bilayer graphene which forms repeating patterns. “This discovery makes fabrication easier, avoiding the challenge of ensuring the precise twist angle that bilayer graphene requires,” said Mohammad Babar, the first author of the study.
