EOY Report - PART III Provides the Division with material to defend and support current and future research in the field. We use atomic-scale measurements to assess the success of deposition, assembly, and design of molecular components. The inset shows the design of a molecular switch which can be activated with an electric field. We have also performed XPS and in our collaboration with the Allara group infrared spectroscopy. We have also done tunneling spectroscopy to show the gap associated with the base.
Caltrops are to serve as a base of attachment for the molecular switches.
Our initial deposition procedures appear to suffer from two difficulties. The first is incomplete reactivity with the surface. This is apparent from the XPS spectra in which two distinct S doublets are found. We assign these to S being reacted and not with the surface. There is no evidence the S is oxidized.
