2016-2017 Georgia Tech Institute for Electronics and Nanotechnology (IEN) Seed Grant Program: Spring 2017 Information and Request for Applications

Program Description

The Georgia Tech IEN is an Interdisciplinary Research Institute (IRI) comprised of faculty and students interested in using the most advanced fabrication and characterization tools, and cleanroom infrastructure, to facilitate research in micro- and nano-scale materials, devices, and systems. Applications of this research span all disciplines in science and engineering with particular emphasis on biomedicine, electronics, optoelectronics and photonics, and energy applications. As there can be a learning curve associated with initial proof-of-concept development and testing using cleanroom tools, this seed grant program was developed to expedite the initiation of new graduate students and new research projects into productive activity. Successful proposals to this program will identify a new, currently-unfunded research idea that requires cleanroom access to generate preliminary data necessary to pursue other funding avenues.

Tiny  Buzz = Big 3D Print Capability for IEN Users

This statuesque Buzz placed in front of a dime is only 1mm tall. The mini mascot was created by Devin Brown on the Nanoscribe Photonic Professional GT 3D-Direct Laser Write (DLW) system. This newest tool in the IEN set  can write arbitrarily-shaped, three-dimensional patterns into light-sensitive polymer films with a lateral resolution down to 150 nm. The tool complements existing optical and e-beam lithography tools available at Georgia Tech and will enable the fabrication of a wide variety of 3D micro- and nanostructures and their integration into devices and systems.

Awards Updates March 2017

Congratulations to Wenshan Cai, a recipient of an Office of Naval Research Young Investigator Award for his project entitled “Hot-Carrier-Induced Nonlinear Optical Processes in Photonic Metamaterials.” His research aims to leverage the ultrafast dynamics of plasmonic-induced hot-carriers at the interface of nanostructured metals and electron-acceptor-materials to establish a fundamentally new paradigm for all-optical, spectrally tunable, and sup-picosecond control of nonlinear optical processes in plasmonic metamaterials for signal generation and data processing.

CtrLayer Sputterer Raises the Bar for IEN Metal Deposition
Sometimes when a problem is solved a greater opportunity presents itself. When the heavily used Unifilm sputterer began showing its age it was determined that a major overhaul was required to give the tool a second life.  So much of the tool used integrated components that were no longer produced, a high potential was recognized in which one small parts failure might cause the whole system to be ill repairable.  During the completing of a 3 phased upgrade process the IEN technical staff realized that through this process it was now possible to build a similar system. The project to build a new tool is a large undertaking but something the IEN technical staff has been successful at completing time and time again. With only the knowledge developed over the Unifilm upgrades, the project started with nearly a blank slate.  A new chamber was designed and constructed, mated to it was a new pressure control system and hoist mechanism. But the real advancement came inside of the chamber. The Unfilm, and now corresponding CtrLayer SDS, utilized a timed osculating orbital sample motion system to provide some of the highest quality sputtered films achievable. Using a series of inter-rotating plates and a thickness-motion algorithm developed by the IEN technical staff, The CtrLayer is capable of precisely transport and rotate samples through the sputtering area to ensure deposited film uniformity of 2% over a 4” substrate. Now, the addition of a High Power Impulse Magnetron Sputtering (HIPIMS) unit to the CtrLayer SDS has given the tool an even greater breath of capability. This new technique of cycling high pulse power at a rapid rate gives the tool the ability to deposit a new array of material compositions. Work is currently underway on the development and characterization of a Aluminum Nitride deposition process focused on C-Axis crystallinity for piezoelectric applications.

Education & Outreach
IEN Hosts Elementary School Nanotechnology Outreach

As part of IEN’s mission of preparing the future workforce and increasing public understanding and knowledge about nanotechnology research and its real-world impacts, IEN hosted a Nano-day experience at Paulding County’s Allgood Elementary School. A group of 153 5th graders, 6 full-time instructors, 3 assistant instructors and 3 parents participated in an event that was kicked off by a presentation, “Nanotechnology, it's a Small, Small, Small, Small, Small, Small, Small, Small, Small, (10-9), Different Behaving World”. After the presentation, the participants had the chance to experiment with hands-on activities involving hydrophobic properties & ferromagnetics, as well as a chance to view various nanoscale features of items, such as insects and pollen, under a scanning electron microscope (SEM).

 IEN Technical Seminar Series:
Advances in Parylene Technology for Improving Reliability for Innovative Technology - Dr. Rakesh Kumar 

Tuesday March 7, 2017
12:00 PM EST

Marcus Nanotechnology Building | 345 Ferst Drive | Atlanta, GA 30332

The role of polymers in the electronics and medical arenas, particularly in miniaturized devices and electronic components, continues to grow rapidly. As the number of medical devices and electronics are growing to enhance human life, the challenges to make them safe, effective, and to find protection solutions for components are also increasing. For a number of years, conformal coatings have offered a level of protection to components, but many simply do not offer the level that is required for today and tomorrow's complex technologies.

This presentation will provide an overview of recent advances in Parylene technologies, including microRESIST® Antimicrobial Parylene Technology, and will discuss how currently available Parylenes differentiate themselves from other available conformal coating and polymeric materials. This presentation will address the latest advances in adhesion technologies and Parylene's role in nano- and micro- technologies. Examples of applications that have benefited from the properties of Parylene include circuit card assemblies, MEMS, LEDs, sensors, lab-on- a-chip devices, pacemakers, stents, electrosurgical tools, cochlear implants, neurostimulation devices and elastomers.

As applications and materials continue to evolve, Parylenes, used as conformal coatings as well as structural materials, enhance the performance and reliability of critical components and devices.

Speaker Bio: Dr. Rakesh Kumar is currently the Vice President of Technology for Specialty Coating Systems, Inc., overseeing Parylene R&D activities worldwide. With more than 27 years of extensive experience in polymeric materials, Dr. Kumar is currently involved with the application of Parylenes in the fields of medical devices, electronics, MEMS, sensors and nanotechnology. Dr. Kumar earned his doctoral degrees in Chemistry from India, and completed his post-doctorate work at the University College London, United Kingdom. He is co-author of a book and has authored several published papers and patents.
