Sub-Atomic Scale Letters


Letters drawn at sub-atomic scale by researchers Hari Manoharan, Laila Mattos, and Chris Moon – carbon monoxide atoms placed carefully on a copper substrate, whose interference patterns resolve into letters. A very cool addition: the letters S and U (for Stanford University, where the research took place) are actually encoded on top of each other.

See this NSF page for a video explaining the process in detail.
