Self-assembled monolayers of 1-Octanethiol on a gold/mica substrate

STM images on self-assembled monolayers (SAMs) of 1-octanethiol on a gold/mica substrate.

Data recorded by Erin Iski of the Sykes Group at Tufts University, MA, USA.

150x150nm image

The sulfur atom binds to the surface it removes gold atoms and single atom deep etch pits are formed.

6x6nm image

Individual molecules can be discerned.
