Prof. Filler visited Princeton University to give the student-selected seminar in the Department of Chemical and Biological Engineering.
A new collaboration with Jerry Shan and Leonard Feldman at Rutgers University has been funded by the National Science Foundation. The project seeks to understand and control statistical variations in the conductivity of semiconductor nanowires. Thanks NSF!
Elizabeth Tom, a summer student in the Filler lab, won the best presentation award at the SURE year-end research symposium. Congratulations. Enjoy that iPad!
Saujan Sivaram, a recent graduate of the Filler Lab, has been awarded a National Research Council (NRC) Postdoctoral Fellowship. He will be working at the Naval Research Lab (NRL) in Washington, D.C. Congrats!
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.
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 have successfully passed the Ph.D. qualifying exam and have been officially admitted to Ph.D. candidacy. Congratulations!
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: firstname.lastname@example.org
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.
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 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.
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.
Happy New Year! Our latest lab photo in front of the Marcus Nanotechnology Building (our new home).
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!
The Filler lab just relocated to the 2nd floor of the Marcus Nanotechnology Building. Come visit us!
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 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.
