Therefore, single molecule conductance measurements provide experimental evidence for theoretically expected behavior which cannot be determined by any other means but single molecule analysis. [Pg.128]

Ultimately electronics will consist of networks of molecules. Single molecule conductivity measurement was first done by using a scaiming tunneling microscope (STM) tip positioned above a molecule adsorbed to a metallic or semi-conducting surface [10] (Figures 10,11). [Pg.151]

A natural extension of the STM break junction technique was to perform analogous experiments using an EC-STM setup, allowing conductance measurements and single molecule trapping in electrolyte solutions. Haiss et al. were the first to accomplish this with their 2003 report on single molecule conductance measurements in a phosphate buffer solution for a 4,4 - bipyridinium derivative... [Pg.733]

Figure 7-20. An illustration of the conducting AFM developed by Cui et al. for measuring single molecule conductance. Figure 7-20. An illustration of the conducting AFM developed by Cui et al. for measuring single molecule conductance.
The conducting AFM method has revealed interesting details of the single molecule conductance of carotene molecules. The electronic properties of carotenoids are of interest since they play a role in their biological function, especially their optical properties which are a manifestation of their delocalised electron structure. The structure of the dithiolated carotenoid used in a study by Ramachandran et al. is shown in Fig. 7-21. A synthetic molecular wire 2,5-di(phenylethynyl-4 -thioacetyl)benzene, also appraised by conducting AFM is also shown in Fig. 7-21. The measured low bias resistance of the carotenoid molecule was found to be (4.9 0.2) GQ. After... [Pg.230]

Haiss et al. have also demonstrated how single molecule conductance can be measured in electrolyte solution as a function of electrode potential. " This offers the ability to perform more defined measurements of single... [Pg.234]
