Abstract

Nano-holes, etched under an electron beam at room temperature in singlelayer graphene sheets as a result of their interaction with metalimpurities, are shown to heal spontaneously by filling up with either non-hexagon, graphene-like, or perfect hexagon 2D structures. Scanning transmission electron microscopy was employed to capture the healing process and study atom-by-atom the re-grown structure. A combination of these nano-scale etching and re-knitting processes could lead to new graphene tailoring approaches.

    • Some graphene facts that I've found after a few minutes of research: - One million times thinner than paper, one atom thick, it's considered a 2D material. http://www.chemistryviews.org/details/ezine/4976821/Is_Graph... - Strongest material, stronger than diamond.…
