An atomic force microscopy topograph with a long and narrow (≈24 µm × 37 nm) graphene nanoribbon emerging from a graphite flake laying on a silicon oxide substrate is shown in the image. The sample is prepared by microcleavage using silicone stamps instead of cellophane tape. These nanoribbons present well‐defined edges along the graphite crystallographic directions.
