The Filler lab welcomes two new Ph.D. students: Maritza Mujica and Amar Mohabir. Maritza received her undergraduate degree from Arizona State University. She will focus on nanowire scale-up and will be co-advised by Drs. Behrens and Breedveld. Amar received his undergraduate degree from the University of Florida and will be studying nanowire thermal transport.
Ho Yee's manuscript accepted to Nano Letters
Ho Yee's manuscript titled “Solid-Liquid-Vapor Etching of Semiconductor Nanowires” has been accepted for publication in Nano Letters. He demonstrated that semiconductor atoms could be chemically removed from the catalyst droplet that directs nanowire growth. This long-suspected process opens new avenues to spatially control nanowire composition, create kinks with user-selectable angles, and even “heal” damaged nanowires.
Prof. Filler visits the Naval Research Laboratory
Prof. Filler presented a seminar, titled “Deep Sub-wavelength Localization of Infrared Light in Semiconductor Nanowires,” at the U.S. Naval Research Laboratory on September 3, 2015 in Washington, D.C.
Saujan's manuscript accepted to JACS!
Saujan's manuscript titled "Direct Observation of Transient Surface Species during Ge Nanowire Growth and their Influence on Growth Stability" has been accepted for publication in the Journal of the American Chemical Society. This work uses in situ infrared spectroscopy during the growth of semiconductor nanowires to show that surface adsorbates present on the sidewall are required for stable growth. These findings suggest new opportunities to control nanowire growth and improve structure.
Jon Gaul wins AIChE award
Jonathan Gaul has won the 2014-15 Donald F. Othmer Sophomore Academic Excellence Award from AIChE. The award is based on academic performance and will allow him to attend the 2015 AIChE meeting in Salt Lake City, UT to present his undergraduate research.
Congrats!
Dr. Filler awarded NSF grant
Dr. Filler has been awarded a National Science Foundation grant for a proposal titled “Deep Sub-wavelength Thermal Radiation Localization and Transport.” The 3-year award will allow the Filler Lab to explore how surface plasmon resonances supported in semiconductor nanowires can interact with and direct the flow of thermal radiation (i.e., infrared photons).
Dmitriy wins poster award at SERES III symposium
Dmitriy Boyuk won 3rd place for his poster at the 3rd Annual SouthEast Regional Symposium. Great work!
Saujan successfully defends his Ph.D. thesis
Congratulations to Dr. Saujan Sivaram for successfully defending his dissertation titled “The Impact of Surface Chemistry on Stable Semiconductor Nanowire Growth.”
Dr. Filler awarded tenure at GT!
Dr. Filler has been promoted, effective July 1st, 2015, to the rank of Associate Professor with tenure.
Prof. Filler wins GT-FIRE seed grant
Prof. Filler has been awarded a GT-FIRE seed grant for his proposal titled “Thermoplasmonic Energy Conversion: A New Paradigm for Harvesting Waste Heat.”
Dmitriy and Li-Wei’s manuscript accepted to ACS Nano
Congratulations to Dmitriy and Li-Wei, whose manuscript titled “Optically Abrupt Localized Surface Plasmon Resonances in Si Nanowires by Mitigation of Carrier Density Gradients” was just accepted to ACS Nano. This work examines the impact of axial carrier density gradients on localized surface plasmon resonances (LSPRs). Control of carrier density profile is critical for controlling plasmonic response in nanoscale semiconductors and for achieving large field enhancements in the near-field. Great work!
