Nano@Tech: Michael Filler

*********************************
There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Abstract:
Semiconductor nanowires are promising building blocks for a diverse range of next generation electronic, photonic and energy conversion devices. The physical properties of these materials, and nanostructures in general, are intimately connected to their structure, which must be controlled with atomic-level precision. Unfortunately, the accessible design space remains limited by a reliance on chemistries that were originally developed for 2-D thin film growth. The 3-D nature of nanowires requires new strategies with which to manipulate growth processes and engineer structure. This talk will provide an overview of our recent efforts to advance semiconductor nanowire complexity and function by expanding the available synthetic “toolkit.” Our experimental approach couples the real-time in-situ spectroscopic interrogation of nanowire chemistry with post-growth structural characterization. We connect nanowire crystal structure with the specific chemical bonds present during synthesis and, in doing so, provide a robust foundation from which to rationally achieve novel structural motifs. The role of hydrogen as the root cause of well-known phenomena in Si nanowire growth will be discussed in detail. We subsequently leverage this fundamental knowledge to generate new types of superstructures with user-defined periodicity.

Speakers Bio:
Michael A. Filler is an assistant professor in the School of Chemical and Biomolecular Engineering at Georgia Tech. He received his doctorate in chemical engineering at Stanford University and was a postdoctoral scholar in the Department of Applied Physics at the California Institute of Technology. Filler’s research program lies at the intersection of chemical engineering and materials science, focusing on the synthesis and characterization of next generation electronic and photonic materials. The application of in-situ spectroscopic techniques to understand relevant interface phenomena and rationally engineer nanoscale semiconductors is a major component of his work. Filler has received several honors including the National Science Foundation CAREER Award, Dorothy M. and Earl S. Hoffman Award from the American Vacuum Society and the Georgia Tech CETL/BP Junior Faculty Teaching Excellence Award. He was also an invited speaker at the 2011 NAE EU-US Frontiers of Engineering Conference.
