Saujan's manuscript accepted to Nano Letters
Congratulations to Dr. Saujan Sivaram, the lead author on a manuscript titled "Surface Hydrogen Enables Sub-Eutectic Vapor-Liquid-Solid Semiconductor Nanowire Growth" that was recently accepted to the journal Nano Letters. Along with collaborators Ho Yee Hui, Dr. Maria de la Mata, and Prof. Jordi Arbiol, he showed that nanowire growth while the catalyst droplet is in a sub-cooled liquid state, a widely observed behavior, results from the presence of surface adsorbates that decorate the nanowire sidewall. These species act as a diffusion barrier, preventing the droplet from finding a low-barrier nucleation site. More generally, the ability of surface adsorbates to arbitrate the diffusion of species to/from the catalyst droplet opens new opportunities to choreograph nanowire growth, structure, and function.
Filler Lab contributes to new Lab on a Chip publication
Ho Yee Hui and Prof. Filler are co-authors on a recent Lab on a Chip publication from the Shan group at Rutgers University. Ho Yee synthesized nanowire samples whose carrier density was determined with a new high-throughput, non-contact method called electro-orientation spectroscopy (EOS).
Dmitriy Boyuk wins poster award
Dmitriy Boyuk was one of three poster award winners at the 2016 Institute for Electronics and Nanotechnology (IEN) User Day. Congratulations on yet another award!
Maritza Mujica and Amar Mohabir pass the qualifying exam!
Maritza Mujica and Amar Mohabir have successfully passed the Ph.D. qualifying exam and have been officially admitted to Ph.D. candidacy. Congratulations!
Seeking postdoc applicants!
Martin Maldovan, Bara Cola, and I are in search of a postdoc to initiate a project to demonstrate a solid-state heat mirror.
The ideal candidate would have experience with the vapor deposition (e.g., CVD or MBE) and physicochemical characterization (e.g., Raman, TEM, etc.) of multilayered crystalline materials. However, outstanding students with experience in related research areas (e.g., nanomaterials, thin films, surface science, heat transport fundamentals, etc.) will also be considered.
Interested? Please send your CV to me at: mfiller@gatech.edu
Jon Gaul places 3rd at Air Products poster competition
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.
