ANL Research Highlights

As an Argonne Scholar, I developed a combined top-down/bottom-up methodology to control the long-range ordering of self-assembled nanoscale block copolymer domains. Electron beam and interference lithography were used to topographically pattern substrates with microscopic channels of varying geometry. These patterned surfaces provide direction to the one-dimensional polymer domains, enabling them to self-organize with very low defect densities over macroscopic length scales. Hybrid nanocomposites were then fabricated using these polymer films as scaffolds for patterning magnetic and semiconducting nanoparticles.

In my current position in the Center for Nanoscale Materials, I am working on extending the top-down/bottom-up methodology to a broader class of nanomaterials. The aim of these new endeavors is both to develop novel insights into self-organization in confined environments and to apply this knowledge to technologically significant material systems such as bioscience, optoelectronics, and magnetic recording media.
