Folds or bends in graphene act like construction zones in a superhighway – making it difficult for electric charges to travel smoothly through. Graphene is the thinnest and strongest material known to man, consisting of a single layer of carbon atoms linked in a honeycomb-like arrangement. The material’s structure makes it incredibly conductive. But conditions are not always optimal. In this image, hills and valleys in the electron cloud lining the surface of graphene can act as speed bumps preventing the smooth flow of electric charges. Red regions indicate folds and green regions are relatively flat. The ideal scenario is one that is completely flat, or all green.
