Proje Konusu : The microelectronics revolution sparked by the invention and the very-large-scaleintegration of transistors has affected almost every aspect of our daily lives. As the 50-year-old Moore’xxs law is approaching its limits, scientists are now turning to light as theinformation carrier. Unfortunately, our ability to control light in nanoscopic volumes is inmany ways in its infancy, compared with how we can manipulate electrons. A new class ofoptical materials known as photonic crystals may hold the key to continued progresstowards all-optical integrated circuits. However, traditional nanomanufacturingtechnologies for producing photonic crystals with three-dimensionally orderednanostructures suffer from low throughput, small sample areas, and high cost. Byintegrating a simple, fast, and inexpensive colloidal self-assembly methodology with a newtype of shape memory polymer, this project will explore a novel scalablenanomanufacturing approach for wafer-scale production of photonic crystals withreconfigurable optical properties. This interdisciplinary research will be closely integratedinto curriculum development, new demonstration module design, and training ofunderrepresented high school and undergraduate students through a few successfulprograms at the university.Although various colloidal self-assembly technologies have been developed, most of thesebottom-up approaches are only favorable for low volume, laboratory-scale production ofphotonic crystals. Moreover, self-assembled photonic crystals with fixed microstructuresare only appropriate for fabricating passive nanooptical devices. Smart shape memorypolymers that can memorize and recover their permanent shapes from structurally stabletemporary sates are promising for developing active photonic crystal devices.Unfortunately, most of the existing shape memory polymers are thermoresponsive, andthey suffer from heat-demanding shape memory cycles. The research team aims toconduct simultaneous experimental and theoretical investigations to address the keyscientific and engineering barriers faced by the current colloidal self-assembly and shapememory polymer technologies. In-situ nanoscopic mechanical and mechanochromic tests,along with multiphysics mechanical finite element analysis simulations will facilitate thebasic understanding of the unusual shape recovery mechanisms of the new type of shapememory polymer that enables unconventional all-room-temperature shape memory cycles.The stimuli-responsive microstructure-optical property relationship of the self-assembledphotonic crystals will be elucidated by optical characterization and finite element opticalsimulations. Large-area macroporous polymer photonic crystals with optimal crystalstructures and multiple memorizable optical states will be fabricated by the scalablebottom-up nanomanufacturing technology.

Proje Konusu : Solar energy is clean, abundant, and renewable, but faces challenges mainly due to the high manufacturing and installationcosts of photovoltaic modules. Finding novel fabrication techniques for solar energy conversion that could increase efficiencyand lower manufacturing cost is a primary challenge in meeting the world’xxs future energy needs in a renewable fashion.This project aims to conduct research on a scalable bottom-up nanofabrication platform that enables industrial-scaleproduction of self-cleaning, broadband antireflection coatings on a large variety of photovoltaics-relevant substrates, suchas single-crystalline and multicrystalline silicon, glass, GaAs, and GaSb. This platform combines the simplicity and costbenefits of bottom-up colloidal self-assembly with the scalability and compatibility of top-down microfabrication. Theproposed activity is aimed at enabling less expensive and more efficient crystalline silicon solar cells.The proposed activity, if successful, may lead to reduced manufacturing cost and increased conversion efficiency ofcrystalline silicon solar cells. Improving the conversion efficiency of solar cells facilitates to reduce the environmental impactand the consumption of oil, natural gas, and fossil fuels-generated electricity. Improved fundamental understanding ofsubwavelength-grating diffraction may also result from the proposed research. Besides renewable energy, the scalablebottom-up nanofabrication platform has the potential to advance many other areas that depend on the creation of largeareaperiodic nanostructures, ranging from all-optical integrated circuits to high-efficiency light emitting diodes.

Proje Konusu : This research project aims to develop fundamental understanding of a robustnanomanufacturing technology that combines the simplicity and cost benefits of bottom-upself-assembly with the scalability and compatibility of top-down microfabrication.Spontaneous organization of colloidal nanoparticles with diameter smaller than 100 nm isof great scientific interest and considerable technological importance in developingpractical devices with unprecedented electronic, optical, magnetic, and mechanicalproperties. The research has three objectives: (1) elucidate the basic mechanisms bywhich unusual nonclose-packed nanoparticle assemblies form during a simple spin-coatingprocess, (2) assemble ferromagnetic nanoparticle arrays for ultra-high density magneticrecording, and (3) develop ultra-sensitive chemical and biological sensors by using periodicmetallic nanostructures.If successful, this work will lead to significant breakthroughs in a wide spectrum of fieldsranging from magnetic recording media to biosensors. The scalable assembly of colloidalnanoparticles will advance many other areas not covered by this proposal ranging fromhighly efficient solar cells to bio-microanalysis, where the creation of large-area periodicnanostructures is important. The closely integrated educational plan focuses on developingseveral outreach activities to educate K-12 students as well as general public onfascinating biomimetics and bottom-up nanomanufacturing. An educational display for theFlorida Museum of Natural History’xxs ”Butterfly Rainforest Center” will be created todisseminate the fascinating nanostructures and the associated unique functionalities foundon morpho butterfly wings and butterfly eyes, along with how to mimic thesenanostructured coatings using nanoparticle self-assembly. Direct participation of highschool students from underrepresented groups in the research program will be soughtthrough a successful program at the university.

Proje Konusu : Photonic crystals and plasmonics are two key techniques that will ultimately enablealloptical integrated circuits and quantum information processing. Unfortunately, thedevelopment and implementation of these techniques have been greatly impeded byexpensive and painstaking topdown nanofabrication (e.g., electron-beam lithography),which limit the available sample size to less than 1 mm2. By contrast, bottom-up colloidalself-assembly and templating nanofabrication provide a much simpler, faster, andinexpensive alternative to nanolithography in creating highly ordered photonic crystals andplasmonic nanostructures. However, the traditional colloidal self-assembly and templatingapproach suffers from low throughput, incompatibility with standard microfabrication, andlimited crystal structures which greatly hamper the mass-production and on-chipintegration of practical nanooptical devices.Intellectual Merit. This proposal aims to develop understanding and control of a robustspin-coating technology that combines the simplicity and cost benefits of bottom-up selfassemblywith the scalability and compatibility of top-down microfabrication. This willenable the creation of wafer-scale photonic crystals and a large variety of functionalsubwavelength-structured materials. The research plan has four specific objectives: (1)elucidate the basic crystallization mechanisms by which unusual nonclose-packed colloidalcrystals form during spin-coating, (2) determine the photonic band gap properties ofshear-aligned colloidal photonic crystals, (3) investigate the surface plasmon properties oftemplated periodic metallic nanostructures, including enhanced optical transmissionthrough subwavelength nanohole arrays and surface-enhanced Raman scattering (SERS)on nanovoid gratings, and (4) develop biomimetic subwavelength-structured antireflectioncoatings for high-efficiency solar cells.The proposed experimental and theoretical investigation will lead to significantbreakthroughs in a wide spectrum of fields ranging from all-optical integrated circuits toplasmonic sensors to sustainable energy. Improved fundamental understanding of flowinducedcrystallization and melting within non-uniform shear flows, a topic that hasreceived little or no examination, will also result. The creative and original components ofthe research plan rely on the integration of the above four objectives. Insights gained intobasic mechanisms facilitate better control over the crucial crystalline parameters fortailoring the optical properties in the later objectives. Most importantly, the periodicplasmonic nanostructures and subwavelength-structured antireflection coatings are indeed2-D photonic crystals, and are thus studied with similar experimental (opticalspectroscopy) and modeling (rigorous coupled-wave analysis) techniques as photoniccrystals. The unification of these apparently different but intrinsically interconnected fieldsunder one umbrella ? the spin-coating platform could lead to new optical features that areinteresting fundamentally and technologically.
