True Atomic Resolution on Calcite
Three sequential images show the repeatability of atomic scale defects on the cleavage plane of a calcite crystal imaged in water with the Cypher AFM. The images were taken in AC mode (open loop, corrected for piezo creep) with a cantilever amplitude of 1 Angstrom. Image size: 10 nm. Height scale: 1 Angstrom. Phase scale: 60 degrees.
