William G. Spitzer Lecture Series

William G. Spitzer

The Spitzer Lecture was named in honor of physicist William G. Spitzer, who was a member of the USC Viterbi School faculty from 1963-1993.

Renowned in the field of semiconductor physics, Spitzer was the founding chair of the Viterbi School’s original Materials Science Department, and known for his pioneering contributions to the understanding of free carrier absorption, plasmon-phonon coupling, local mode absorption and transport across Schottky barriers. He later served as chair of the Physics Department (1969-72), dean of Natural Sciences (1983-89), and interim provost (1993).

In 1969, Spitzer was awarded the USC Research Award. In 1982, he received the USC Raubenheimer Distinguished Faculty Award and, in 1989, USC bestowed on him its highest honor, the USC Presidential Medallion.

Spitzer’s son, Matthew Spitzer, thanked the Viterbi School and the Mork Family Department of Chemical Engineering and Materials Science for creating the annual Spitzer Lecture as a tribute to his father.

“Integrated Bioelectronic Systems”

February 2, 2012

Abstract

High performance microelectronic systems and bioelectrochemical systems are both highly developed, complex systems capable of advanced signal processing and computing – yet are fundamentally different at nearly every level (mechanism, device, architecture, etc). A major step in understanding these differences will be the ability to effectively interface between these systems. This talk will review the recent progress, the outstanding scientific challenges, and some exciting potential applications in this rapidly growing new field.

“New Photonic Material Designs for Solar Energy Conversion”

Thursday, January 20, 2011

Abstract

Solar energy is currently enjoying substantial growth and investment, owing to worldwide sensitivity to energy security and climate change , and this has spurred basic research on light-matter interactions relevant to solar energy. Professor Atwater will describe approaches to control of light-matter interactions leading to enhanced light-trapping and absorption, as well as increased open circuit voltage and enhanced quantum efficiency in solar photovoltaic structures. Conventionally, photovoltaic cells have a physical thickness comparable to their ‘optical thickness’ for full light absorption and photocarrier current collection. Solar cell design and material synthesis considerations are strongly dictated by this simple optical thickness requirement. Dramatically reducing the absorber layer thickness or volume confers several fundamental and practical benefits, including increased open circuit voltage and conversion efficiency, and also expansion of the scope and quality of absorber materials that are suitable for photovoltaics. He will describe light absorption in thin film and wire array solar cells that demonstrate enhanced absorption compared with conventional photovoltaic cells, and limits to enhanced absorption will be explored. Plasmonics and metamaterials design can also be exploited advantageously in photovoltaics. He will describe design approaches using metallic nanostructures to enhance the radiative emission rate and hence also the photovoltaic material quantum efficiency relative to conventional light-trapping structures. Finally, future design metamaterials for broadband resonant absorption and spectrum-splitting will be discussed.

 Challenge to Seeing Atomic Structures of Nano-materials with Electron Microscopy
 

Lecture Poster

Monday, March 22, 2010

ABSTRACT

Nanoscience deals with nano-scale structures of materials and therefore controlling the structures is crucial. A typical example of nanostructures is carbon nanotubes and their many unique properties have been investigated theoretically and experimentally, and brought a new concept of materials into condensed matter physics. More importantly, nanoscience is closely related to nanotechnology and thus to industrial applications as we see in many fields of carbon nanotube research. 

An important issue for nanoscience is characterization of materials. In the case of carbon nanotubes their exact atomic structures are determined by means of electron microscopy, Raman and photoluminescence spectroscopy, etc., where sometimes commercially available instruments are not sufficient and need substantial modification for each particular purpose, where “do it yourself” becomes important. 

We demonstrate some latest results on structural characterization of carbon nanotubes, graphene, and boron nitride thin films, including “monatomic carbon strings that have been successfully observed in our laboratory.

Sumio Iijima is a Professor at Meijo University, a Director of the Nano-tube Research Center at AIST and a Senior Research Fellow at NEC, in Japan. After graduating from Tohoku University, he joined Arizona State University where he developed high-resolution transmission electron microscopy (HRTEM) (1970-1982). In 1982 he returned to Japan and joined the NEC Research Laboratories in 1987. In 1991 he discovered carbon nanotubes that have initiated nano-material science and nanotechnology.

Abstract

Simplicity and economy are often the keys to successful technologies. “Simple solutions” is the phrase we apply to the idea of using science to provide easily used solution to a variety of problems in bioanalysis, with a particular focus on problems in developing economies. The requirements for low cost, ruggedness, and independence of infrastructure characteristic of problems in developing economies pose remarkably challenging problems for advanced science and technology—and the area is one that will benefit enormously from new ideas. Successful solutions will also be useful both in developing economies and in the developed world: low cost and simplicity are advantages almost everywhere. The flow of problems, ideas, and solutions stimulated by considering these problems is thus a most interesting two-way street. This talk will discuss this class of problems within the specific context of medical diagnostics (how close can one come to “Zero-cost Diagnostics”?), and with a focus on three technologies: microfluidic systems based on patterned paper, microanalytical systems using magnetic levitation, and simple microfluidics devices for use with simple organisms.

NanoSystems Biology and New Technologies for in vitro and in vivo Diagnostics of Cancer

Abstract

The emerging world of personalized, preventative, predictive, and participatory (P4) medicine will likely be enabled by the developing field of systems biology. Systems biology and P4 medicine both data driven and, accordingly, both require new tools for making large numbers of measurements rapidly, quantitatively, and inexpensively. Microfluidics, chemical, and nanotechnologies will revolutionize our ability to generate comprehensive data sets that span from individual cells to patients, and will allow us to build multiparameter analysis tools (quantitating genes, proteins, and cells) for achieving an informative in vitro disease diagnosis, as well as in vivo molecular imaging probes for spatially localizing specific diseases. Using cancer as a theme, I will describe the state-of-the-art in terms of network models of human diseases, and I will describe how those models may be harnessed for information that can impact clinical care of cancer. I will then describe a suite of in vitro and in vivo multiparameter diagnostics technologies that we are developing in my lab in concert with other groups, in the context of both near term and far term applications.
