Congratulations to Jon Gaul for his third place finish at the annual Air Products ChBE Undergraduate Research Symposium! His poster was titled, "Modifying Synthetic Techniques for Higher Energy Plasmon Resonance." In the photo below, Jon is on the far right below.
Martin Ek joins the Filler Lab
We are delighted to welcome Dr. Martin Ek to the Filler Lab. He received his Ph.D. at Lund University in Sweden and then worked at Haldor Topsøe in Denmark. Martin will be studying the surface chemistry of semiconductor nanowires.
The Nanovation Podcast launches!
The Nanovation podcast is a forum to address the big questions, big challenges, and big opportunities of nanotechnology. Discussion topics will lie at the intersection of nanoscience, manufacturing, technology, innovation, business, and society. The podcast is conversational in format, only mildly edited, and will often involve expert guests. It is aimed at a general, but technically-savvy audience. Find out more here.

Dmitriy's LSPR coupling manuscript accepted to ACS Photonics
Congratulations to Dmitriy Boyuk and co-author Dr. Li-Wei Chou whose manuscript titled "Strong Near-Field Coupling of Plasmonic Resonators Embedded in Si Nanowires" was just accepted for publication in ACS Photonics. They show that the anisotropy of nanowires and the large permittivity of Si in the infrared combine to yield very strong near-field coupling between adjacent localized surface plasmon resonances. This work opens new avenues to engineer deep-subwavelength infrared waveguides, chemical sensors, and photodetectors.
2016 Lab Photo
Happy New Year! Our latest lab photo in front of the Marcus Nanotechnology Building (our new home).
Nanowire surface chemistry highlighted
Georgia Tech released a news story highlighting our recent JACS paper. The story was also re-published at phys.org and R&D Magazine.
Dr. Filler speaks about nanowire plasmonics at 2015 MRS Fall Meeting
Dr. Filler gave an invited talk titled "Deep Sub-wavelength Infrared Light Localization and Transport in Semiconductor Nanowires" at the 2015 MRS Fall Meeting in Boston, MA. His talk was part of Symposium P: Synthesis and Applications of Nanowires and Hybrid 1D-0D/2D/ 3D Semiconductor Nanostructures. Thank you to the symposium organizers for the invitation!
Filler lab moves to Marcus Nanotechnology Building
The Filler lab just relocated to the 2nd floor of the Marcus Nanotechnology Building. Come visit us!
Southeast Nanomanufacturing Executive Roundtable held at GT
Dr. Filler co-organized, with Baratunde Cola (ME), David Gottfried (IEN), and Oliver Brand (IEN), an executive roundtable to develop a roadmap for the creation of a locus of manufacturing of functional nanomaterials in the southeastern region of the United States.
Dr. Filler gives series of talks
Dr. Filler recently gave invited talks at Lund University in Lund, Sweden and the Central European Institute of Technology (CEITEC) in Brno, Czech Republic. Thank you to Drs. Kimberly Dick and Tomas Sikola, respectively, for their kind invitations. Dr. Filler also spoke as a contributor at the Nanowire Growth Workshop in Barcelona, Spain.
Welcome Maritza Mujica and Amar Mohabir
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).
