“Materials for Enabling Nanomanufacturing”
Alshakim Nelson, Ph.D.
University of Washington and IBM Almaden Research Labs
Cosponsored with the Santa Clara Valley section of the American Chemical Society
Nanomanufacturing in the semiconductor industry is driven by our ability to rapidly process and manipulate materials into their required forms. This seminar will highlight some of our work to develop materials for the semiconductor field and beyond. First, core-shell ferrimagnetic nanoparticles (FMNPs) developed for self-assembled magnetic storage media will be presented. While FMNPs are susceptible to magnetically induced aggregation, nanoparticles coated with a diblock copolymer are stable in solution and can easily be processed as thin films. As a result, these core-shell particles are suitable for investigating self-assembly processes for creating prototype magnetic media. Next, a simple and facile strategy for high-throughput directed self-assembly of nanoparticles on lithographically defined substrates via spin-coating will be presented. The two-dimensional arrangements of nanoparticles were formed deterministically in just 30 seconds by the strategic placement of topographical features on a substrate. Finally, the integration of dynamic covalent chemistry into nanoimprint lithography will be discussed.
Dr. Nelson completed his undergraduate studies in chemistry at Pomona College in 1999. He received his Ph.D. in organic chemistry from the University of California at Los Angeles in 2004, where he studied carbohydrate-containing polymers and macrocycles with Professor J. Fraser Stoddart. He was then an NIH postdoctoral fellow at the California Institute of Technology working for Professor Robert Grubbs on olefin metathesis catalysts for the formation of supramolecular ensembles. Dr. Nelson joined IBM Almaden Research Center as a Research Staff Member in 2005, where he focused on synthesizing building blocks that enable large area nanomanufacturing via self-assembly. His research interests also include silicon-based polymers for lithographic applications, magnetic nanoparticles, directed self-assembly of nanoparticles, and hydrogen bonding block copolymers. Dr. Nelson has over 40 publications and 11 issued patents, and in 2011 he was designated as an IBM Master Inventor. In 2012, he became manager of the Nanomaterials Group, which includes the Synthetic Development Lab.
Dr. Alshakim Nelson will join the chemistry department of the University of Washington in the 2015-16 academic year. His research will focus on the synthesis, characterization, and patterning of polymeric and supramolecular materials for the bio-interface.
