"Plasmonics for Sustainability"

Metallic nanoparticles, used since antiquity to impart intense and vibrant color into materials, have more recently become a central tool in the nanoscale manipulation of light. This interest has led to a virtual explosion of new types of metal-based nanoparticles and nanostructures of various shapes and compositions, and has given rise to new strategies to harvest, control, and manipulate light based on metallic nanostructures and their properties. As one begins to assemble metallic nanoparticles into useful building blocks, a striking parallel between the plasmons- the collective electronic oscillations- of these structures and wave functions of simple quantum systems is universally observed. Clusters of metallic nanoparticles behave like coupled oscillators, introducing effects characteristic of systems as diverse as radio frequency transmitters and coupled pendulums into light-driven nanoscale structures. Plasmons decay by producing hot electrons, a property appearing to be highly useful in applications ranging from photodetection to photocatalysis. In particular, new “antenna-reactor” photocatalysts can be designed by combining plasmonic nanoparticles with directly adjacent catalytic particles or materials, rendering the heterocomplexes photocatalytic. While our scientific foundation for the field of Plasmonics has been built on nanoparticles consisting of noble and coinage metals, more recently we have begun to question whether the same, or similar, plasmonic properties can also be realized in more sustainable materials. Sustainable plasmonic materials allow us to envision entirely new applications, for example, direct solar distillation that can provide drinkable water, entirely independent of grid-based electrical power.  

Dr. Naomi Halas is the Stanley C. Moore Professor of Electrical and Computer Engineering at Rice University, with joint appointments in Chemistry, Physics and Astronomy, Bioengineering, and Materials Science and Nanoengineering departments. Prof. Halas graduated from La Salle College with a B.A. in Chemistry. She obtained her M.A. and Ph.D. degrees in Physics from Bryn Mawr College and was a graduate research fellow at the IBM Research Center in Yorktown, NY. She was a postdoctoral associate at AT&T Bell Laboratories prior to joining the Rice faculty. Dr. Halas is a pioneer in the field of plasmonics, creating the concept of the “tunable plasmon” and inventing a family of nanoparticles with resonances spanning the visible and infrared regions of the spectrum. She pursues fundamental studies of plasmonic and nanophotonics systems and their applications in biomedicine, optoelectronics, photocatalysis, chemical sensing and, most recently, solar steam generation with applications in off-grid water treatment. She is the author of more than 300 refereed publications with more than 50,000 Web of Science citations, has more than 15 issued patents, and has presented more than 500 invited talks. Dr. Halas is co-founder of Nanospectra Biosciences, a Houston-based company developing ultralocalized photothermal therapies for cancer, currently in clinical trials. She has been awarded the APS Frank Isakson Prize for Optical Effects in Solids, the R. W. Wood Prize of the OSA, and the APS Julius Lilienfeld Prize for outstanding contributions to physics by a single individual who also has exceptional skills in lecturing to diverse audiences. Halas has been elected to the National Academy of Engineering, the National Academy of Sciences, and the American Academy of Arts and Sciences, and is a fellow of the National Academy of Inventors.

Explicitly Quantum Mechanical Devices and Circuits, Especially in Silicon CMO by Dr. Mark Lee (UT Dallas) Friday, Feb 23
(1 p.m. - 2 p.m.)

From the perspective of a physicist, Si CMOS technology has been operating on the same basic “semi-classical” physics principles established in the 1940's. In the 1980’s the introduction of explicitly quantum mechanical effects into III-V transistors proved transformative in terms of high frequency and low noise performance. However, nothing similar happened in Si CMOS because of significant challenges in fabricating quantum device structures in a manner amenable to industrial fabrication. In this seminar I will describe our efforts to integrate a quantum well (QW) into the inversion channel of Si NMOS transistors fabricated on an industrial 45 nm process line. These transistors use lateral ion implantation to define a QW whose potential depth is controlled by the gate voltage. In these devices we have observed explicit quantum transport signatures in the form of negative differential transconductance (NDT) up to room temperature. The NDT signature results from the gate voltage bringing the QW’s discrete quantized state energies first into and then out of alignment with the drain-source energy. I will present the basic QW CMOS device performance characteristics such as NDT strength, gain, and temperature dependence, and also describe some circuit applications, such as a folding frequency multiplier, that take advantage of the quantum transfer function. Finally, I will discuss the results of quantum device simulations that point out a route towards improved designs for a QW device.


Dr. Mark Lee is Professor of Physics and Materials Science and Physics Department Head at the University of Texas at Dallas (UTD). He is also an affiliated faculty member in the Department of Materials Science & Engineering and in the Texas Analog Center of Excellence (TxACE) at UTD. Prof. Lee received his Ph.D. in Applied Physics from Stanford University in 1991 with a thesis in the field of superconductivity. After a two-year postdoc at the NEC Research Institute in Princeton, NJ where he worked on semiconductor superlattices, he joined the physics faculty at the University of Virginia where he led research into highly correlated electron glasses and terahertz properties of superconductors. In 1999, he joined Bell Laboratories–Lucent Technologies in Murray Hill, NJ as a Member of Technical Staff, where he worked until 2003. Prior to taking up his present position at UTD in September 2010, Prof. Lee was a Principal Member of Technical Staff and Manager of the Center for Integrated Technologies Science Department at Sandia National Laboratories in Albuquerque, NM.

Prof. Lee’s research focuses on electrodynamic and quantum mechanical properties of novel materials, nanomaterials, and electronic and photonic devices. In this context, “electrodynamic” means interactions of a material or device with time-dependent electromagnetic fields ranging in frequency from 10 GHz to ~100 THz. This frequency spectrum spans the range of interest to both current and future telecommunications and computation technologies and to fundamental many-particle quantum correlation energies in solid-state systems. “Quantum mechanical” refers to measuring explicitly quantum phenomena, such as charge or conductance quantization or the existence of forbidden energy gaps. He has done extensive work on high-frequency electrical conductivity in ultra-high mobility 2-dimensional electron gases, non-linear electromagnetic frequency mixing in superconductors, dispersion and loss properties of optically non-linear and high-dielectric constant dielectrics, and quantum and electrodynamic properties of interacting electron glasses. For accomplishments in physics research, Prof. Lee was named a Fellow of the American Physical Society (APS) in 2005 and Chair of the APS Forum on Industrial & Applied Physics in 2008.
