Heads and Tails: Simultaneous Exposed and Buried Interface Imaging of Monolayers
Source abstract
Abstract
We have simultaneously imaged the chemically bound head groups and exposed tail groups in bicomponent alkanethiolate self-assembled monolayers on Au{111} with molecular resolution. This has enabled us to resolve the controversy of scanning tunneling microscopy image interpretation and to measure the molecular polar tilt and azimuthal angles. Our local measurements demonstrate that ordered domains with different superstructures also have varied buried sulfur head group structures.

32. While direction g inFigure3ashows very good agreement between δC8/δC6andlC8/lC6, directions i and k inFigure3bshow a larger δC8/δC6deviation fromlC8/lC6. We believe this is caused by a slight thermal drift during the data acquisition ofFigure3b, in the direction parallel to the tilt direction. This is evident from the vertical stretch of the figure. In effect, this thermal drift caused some data loss for our tilt measurement.
