Topological nanoribbon superlattice

Scanning tunneling microscope image of a topological nanoribbon superlattice. Electrons are trapped at the interfaces between wide ribbon segments and narrow ribbon segments. The wide segments are nine carbon atoms across (1.65 nanometers) while the narrow segments are only seven carbon atoms ...This is an NSF Multimedia Gallery item.
