title: Sub-picometer structural information of graphene hidden in a 50 pm resolved image.
abstract: In a 2D self-organized crystalline structure more than 1000 unit-cells can be observed in a single image. Here we exploit the benefits from having a large number of observations of the same unit cell utilizing an image processing methodology. We obtain sub-picometer resolution data from a 50 pm image of graphene, revealing a 1% axial elongation and a 3 fold symmetry, indicating a chair conformation.
