摘要: In a very short time the scanning tunnelling microscope has become an important tool in surface science, and physics general1–3. Its primary use been to obtain atomic-resolution images of surfaces, but recently, efforts have made it manipulate materials as well image them4–10. One may now reasonably ask if is possible move alter matter predictably on atomic scale. Here we report accomplishment smallest yet, purposeful, spatially localized changes matter, effected graphite surface. We believe that result from pinning individual organic molecules graphite. The reverse manipulation, removal pinned molecules, also demonstrated. Finally, evidence can remove portion molecule, effectively performing transformations single using microscope.
