Research in the Inorganic Nanostructures Facility

The Inorganic Nanostructures Facility’s mission is to provide Users with expertise and instrumentation in the areas of synthesis and characterization of nanocrystals, nanotubes and nanowires, The staff conducts a rigorous internal research program on the preparation, characterization and applications of novel inorganic nanomaterials, which continually provides Users with new resources.

This facility studies the science of optimally preparing and characterizing metal, semiconductor, magnetic, insulating inorganic nanostructures, and multi-component nanostructures with various interfaces, including nanocrystals, nanotubes and nanowires with controlled size, shape, connectivity and topology, both internally and with Users. The program encompasses the design and synthesis of precursors, the study of microscopic elementary processes in nanostructure nucleation and growth, and the use of nanostructures in functional, multi-component devices, Robotic synthesis and novel nanocrystal superlattice are of particular interest.

The research of the Inorganic Nanostructures Facility is well integrated with the overall scientific themes pursued throughout the Molecular Foundry, The Organic-Inorganic Interface is critical to every aspect of the synthesis and assembly of nanoscale particles and wires, Organic molecules guide the size and shape of inorganic nanocrystals through selective adhesion and play a critical role in their assembly into arrays. Superlattices of nanocrystal are an intense interest of this facility and are one example of the Foundry’s Supramolecular Assembly theme, The third central Foundry theme is Single Digit Nano, The ability to manipulate the coupling and interaction between two inorganic building blocks, be it a nanocrystal and a nanowire or two types of nanocrystal, depends critically upon control of the single digit nano size molecular species that separate, link and join them together.
