Frontiers in Science Lecture: Celebrating Silicon: Its Success, Hidden History, and Next Act

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.

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).

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.

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. 

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.
