WebAnd you might guess, oh, you know, Sal already told me they're very small. So maybe there's 1,000 carbon atoms there, or 10,000, or 100,000. I would say, no. There are 1 million carbon atoms, or you could string 1 million carbon atoms across the width of the average human hair. That's obviously an approximation. It's not exactly 1 million.

Web6 nov. 2016 · The resolution of an AFM is basically determined by how sharp the tip is, and with a tip that truncates with a single atom, one can have an atomic resolution. So the way these images are made is by scanning an extremely sharp tip across a surface and measuring at each point either the force exerted on the tip or the height of the surface. free thumbnail maker no watermark
