Flying over Atoms: Biothiophene Surface

Low Coverage Bithiophene

Compare the surface image above with an image created with Vistapro.

This surface is a Ag surface with a small amount of 2,2'-bithiophene adsorbed on the surface. The bithiophene molecules appear as elongated "hot-dog" shaped features on the surface. STM shows the molecules bond only at the edges of steps on the surface. The orientation of individual bithiophene molecules is also resolved and they align with the long molecular axis parallel to the step edge direction. Image size is 250 angstroms x 250 angstroms.
