Are the samples cooled to near zero when scanning like this? As far as I understand, even slight temperatures cause molecules to move at ridiculous speeds.
They said it was a 20-hour scan, at 5K, with the AFM tip 0.5 nanometers from the pentacene molecule. The molecule itself is 1.4 nm long, so they were only about 30% of its length away from it in the vertical direction.
