Cool nanotech image — atomic moire pattern of graphene

Check this out:

Caption: Moiré patterns appear when two or more periodic grids are overlaid slightly askew, which creates a new larger periodic pattern. Researchers from NIST and Georgia Tech imaged and interpreted the moiré patterns created by overlaid sheets of graphene to determine how the lattices of the individual sheets were stacked in relation to one another and to find subtle strains in the regions of bulges or wrinkles in the sheets.

  1. The two sheets appear to be some sort of computer graphic of the dogma atomic placement of the carbons. The same sheet twice. I expect that the graphene pores or hexagons divide into two equivalence classes and when the image shows this, it is refocused to show the expected result.. a blur better suggesting perfect equivalence.
