This pair of scanning tunneling microscope (STM) images shows the basic operation of the molecule cascade.


 


Molecule cascade: Chevron basic operation #1
Six carbon monoxide (CO) molecules on a copper surface are shown: a lone molecule, an adjacent pair and a trio in a v-shaped "chevron" arrangement, which is metastable. Red circles indicate CO molecules and blue dots indicate atoms in the underlying copper surface.
