Mesas, ridges and pits on a copper surface

The image was taken with a scanning tunneling microscope that was built by Benedict Drevniok in the Department of Physics, Engineering Physics and Astronomy at Queen’s University. It depicts a copper surface that had been bombarded with Argon atoms. This creates a surface that is pitted (dark blue color). The originally flat surface ends up with this interesting structure. Material is displaced from the pits, creating mesas and ridges (gold color). The steps on the surface are only one atom in height. The image shows a region that is approximately one micrometre in width and height.
