Inorganic nanostructures Facility

Delia Milliron,
Facility Director

Overview

This facility provides instruments and techniques for the comprehensive study of the science of metal, carbon and semiconductor nanostructures. The program  encompasses the design and synthesis of precursors, the study of microscopic elementary processes in nanostructure  nucleation and growth, and the modeling of growth processes. The facility prepares nanocrystals, nanotubes and nanowires with controlled size, shape, connectivity and topology, and Inhouse methods permit the fabrication of hollow, branched and epitaxial nanostructures, as well as nanocrystal superlattices and supercrystals.  Materials are synthesized in both the liquid and gas phases, using primarily colloidal techniques and chemical vapor deposition.
