The objective of this program was to examine the electronic and physico-chemical properties, the stability, and the dynamics of nanometer-scale structures and of components that may be used in such structures. These structures and components may play key roles in evolving or even revolutionizing devices for communications, sensors, and detectors. Our understanding of these structures is developed using unique scanning tunneling microscopy instrumentation which gives us the ability to work at low temperatures, to manipulate surface structures, and to probe both electronically and over a broad frequency range. We collaborate with key developers of molecules, films, and devices to screen and to advance the properties of the components, structures, and films they create. This work serves as the scientific backbone of the technological advances in related DARPA Moletronics work and in a wide range of other areas.
We have learned to manipulate defects, domains, crystallinity, desorption, exchange, insertion, grafting, conductance, and deposition to advantage in order to manipulate film structures and properties and to isolate molecules for use, study, and/or reaction.1-8 We have used scanning tunneling microscopy, X-ray photoelectron spectroscopy, and infrared spectroscopy to measure the resultant films.
We have enhanced our abilities to measure with sub-nanometer resolution across a broad spectral range.8-11 We have discovered unique opportunities at this scale, such as "optically hot" asperities on asymmetric nanoparticles. We expect to be able to exploit these effects to advantage. There are no other means of studying such materials at these scales. Couplings between molecules and nanoparticles that we propose to study may pose fundamental limitations on the densities to which functional devices can be packed.
We have demonstrated our ability to discriminate between different nanostructure compositions. We have proposed using this capability to develop selective "stains" for scanning probe microscopy in analogy to those employed in conventional light microscopy.9,10 The difference here is that much higher spatial resolution will be possible so that single exposed functional groups may be labeled.
Specific accomplishments relating to the above are:
Selecting the separation or mixing of components at the nanometer scale.4,7 In addition, we can graft one film onto another in two dimensions. This enables selective decoration or reaction of unique surface sites at an interface that is physically perfect, but chemically distinct from the rest of the surface.4,7
Selective removal of specific defects by processing films and controlling their completeness.1,4,7 This leads to independent control of insertion, exchange, and removal of molecules.
Insertion of single molecules for subsequent study or reaction.3,8,11 These molecules can then be probed individually or in bundles.8,11 Recent (unpublished) experiments allow us to follow electronic switching of inserted molecules. This isolation also enabled the first example of the selective chemical modification of surface species without disrupting the nanometer-scale structure.3 A living polymer was grown off inserted, isolated tethers. It was also possible to bundle together the tethers so as to select growth of surface-bound polymer brushes. These polymers and the controlled substrate on which they lie may be used to create non-volatile nanometer-scale organic memory.2
We have observed "optically hot" regions on single nanoparticles.9,10 These may be used to enhance spectroscopy, optical coupling at the nanometer scale, or isolation at this scale. We have also shown that nanoparticles couple electronically as they are brought into proximity, but remain out of chemical contact (not yet published). We have created a unique system for studying these interactions that does not depend on bulk synthesis and laborious separations. This will allow us to explore the phase space of these interactions and their dependence on separation and orientation, before targeting selected assemblies for synthesis.
Our ONR Program has served as the core for discovery in our group, from which a large number of other efforts have emanated.
