Prof. Filler will be giving a Frontiers in Science public lecture on March 5, 2019 at 6:30pm in the Marcus Nanotechnology Building as part of Georgia Tech’s activities for the International Year of the Periodic Table. His lecture, titled Celebrating Silicon: Its Success, Hidden History, and Next Act, will take the audience on a journey through the manufacturing innovations that transformed silicon from its humble beginnings as the most abundant metal in Earth’s crust to the enabler of the computer chips that underpin the modern economy. More information is available here and here.
Prof. Filler visits LSU
Prof. Filler visited the Cain Department of Chemical Engineering at beautiful Louisiana State University (LSU) on Friday, January 18, 2019. Thanks to Prof. Kevin McPeak for the invitation and for hosting a wonderful visit.
The Filler Lab represents at the 2018 Fall MRS Meeting!
Recent work from the Filler Lab was on display at the 2018 Fall MRS Meeting. Amar Mohabir talked about his work on Si/Ge nanowire patterning, Maritza Mujica presented her work on the Geode process for large-scale nanowire production, and Gozde Tutuncuoglu discussed her studies of thermal transport in Si nanowires. Prof. Filler was a co-organizer of Symposium NM03: Nanowires and Related 1-D Nanostructures where this work was presented.
The team also left time for a little fun and to meet a few lab alumni! From left-to-right: Prof. Filler, Naechul Shin (Inha University), Gozde Tutuncuoglu, Maritza Mujica, Amar Mohabir, Saujan Sivaram (Naval Research Laboratory), Hyewon Shim (masters student in Naechul’s lab).

Maritza Mujica presents at AIChE
Maritza Mujica presented a talk titled “Advanced Emulsion-Templating of Microreactors for the Scalable Production of Semiconductor Nanowires” at the 2018 AIChE Annual Meeting. In this work, she developed a process to create bulk quantities of hollow microcapsules to use as reactors for semiconductor nanowire growth.
Amar Mohabir presents at AVS
Amar Mohabir presented his work on the bottom-up patterning Si and Ge nanowires at the 65th AVS Symposium and Exhibition in Long Beach, CA. The title of his talk was “Selective Patterning of Silicon/Germanium Surfaces and Nanostructures via Surface Initiated Polymerization.” Trent Weiss and Gozde Tutuncuoglu were coauthors on the work.
Prof. Filler also present a talk titled “The Geode Process: A Route to the Large-Scale Manufacturing of Functionally-Encoded Semiconductor Nanostructures.” This work was completed by Maritza Mujica and is a collaborative effort with the Behrens and Breedveld labs at Georgia Tech. The Geode process uses hollow microcapsules as reactors for semiconductor nanowire growth, allowing nanowire production to be scaled by orders of magnitude.
Prof. Filler visits Tulane and Alabama
Prof. Filler recently visited the Department of Chemistry at Tulane University where he gave a seminar titled “Programming Heterogeneity at the Nanoscale.” Thank you to Igor Rubtsov and his lab for their hospitality.
He also visited the Department of Chemical and Biological Engineering at the University of Alabama where is spoke about “Nanoscale Programming of Semiconductors.” Thanks to Qing Peng for hosting a great visit.
Dr. Filler speaks at the IEEE RAPID conference
Dr. Filler presented two talks at the IEEE Research and Applications of Photonics in Defense (RAPID) Conference. The first was a keynote titled "Scalable Nanophotonics Manufacturing" and second was a focused research presentation titled "Scalable Production and Characterization of Semiconductor Nanowires for Applications in Photonics".
Weize's plasmonic desorption paper accepted to JVST A!
Congratulations to Weize Hu whose paper titled "Enhanced Photodesorption from Near- and Mid-Infrared Plasmonic Nanocrystal Thin Films" was just accepted for publication in the Journal of Vacuum Science and Technology A. It was also chosen as an Editor's Pick! In this work, Weize shows that low energy infrared light coupled to surface plasmons supported by a metal oxide nanocrystal thin film can accelerate the desorption of two model molecules.
Dr. Filler speaks at the National Student Leadership Conference
Weize Hu successfully defends his Ph.D. thesis
Congratulations to Dr. Weize Hu for successfully defending his Ph.D. thesis titled "Surface Chemical Studies of Metal Oxide Nanocrystals Supporting Infrared Localized Surface Plasmon Resonances”. He begins a position at Applied Materials in August.
Celebrating recent lab successes!
Dr. Filler visits UGA
Dr. Filler visited the Department of Physics at the University of Georgia (UGA) where he presented a talk titled "The Vapor-Liquid-Solid Mechanism: Programming Heterogeneity at the Nanoscale." Thanks to Yohannes Abate for hosting such a great visit!
Amy Brummer passes her qualifying exams!
Congratulations to Amy Brummer for successfully passing her qualifying exams. She is now formally a doctoral candidate in the School of Materials Science & Engineering!
Dr. Dmitriy Boyuk

Trent Weiss wins 1st place!
Trent Weiss (second from the left in the picture below) won 1st place at the 2018 Air Products Undergraduate Research Poster Session, beating out more than 25 other undergraduate students. Congratulations!
Dr. Arslan Shehzad joins the group
We welcome Dr. Arslan Shehzad to the lab as our newest postdoc! He hails from Pakistan and completed a Ph.D. in nanotechnology and materials engineering at Sejong University in South Korea. He will be working on a project recently funded by Intel that lies at the intersection of nanowires and 2-D materials.
Amy Brummer wins 2 fellowships!
Congratulations to 1st year student Amy Brummer on being selected for both the NSF (GRFP) and DOD (NDSEG) graduate student fellowships! (In 2018, only 69 NDSEG fellowships were awarded nationwide).
Martin Ek's review article to be featured on journal cover
Martin Ek's review article titled "Atomic-Scale Choreography of Vapor−Liquid−Solid Nanowire Growth" will be featured on the cover of the January 2018 issue of Accounts of Chemical Research. Congrats Martin!
Postdoc opening
The Filler Lab is in search of a postdoc for a new project at the intersection of semiconductor nanowires and 2-D materials. The ideal candidate would have experience in materials synthesis and characterization, and preferably be comfortable with vacuum systems. If you have an interest in such a position and are available to start in the next few months, please email your CV to Prof. Filler.
