The Beckman Institute for Advanced Science and Technology at the University of Illinois at Urbana-Champaign (UIUC) is an inter- and multidisciplinary research institute devoted to basic research in the physical sciences, computation, engineering, biology, behavior, and cognition. The Institute’s primary mission is to foster interdisciplinary work of the highest quality in an environment that transcends many of the limitations inherent in traditional university organizations and structures.

The Beckman Institute’s research is focused around three interrelated main research themes: Biological Intelligence, Human-Computer Intelligent Interaction, and Molecular and Electronic Nanostructures.

Pierre Wiltzius received his Ph.D. in physics from the Swiss Federal Institute of Technology (ETHZ), Zurich, Switzerland in 1981. He was at Bell Laboratories (Lucent Technologies, formerly AT&T) between 1984 and 2001, where he was most recently the Director of Semiconductor Physics Research. He was appointed Director of the Beckman Institute in September 2001; a professor in both the Departments of Materials Science and Engineering, and Physics; and a full-time Beckman Institute faculty member in the Nanoelectronics and Biophotonics Group. His fields of professional interest are soft-condensed matter, colloidal self-assembly, photonic crystals and microphotonics.

Description of Research

Wiltzius' research interests are in self-assembly processes in soft-condensed matter systems, e.g., polymers, liquid crystals and colloids. Colloidal self-assembly, in particular, is a promising approach to build materials for photonics applications. 3-dimensional "photonic crystals" will be building blocks for highly integrated, functional microphotonic devices. Research topics of interest are:

Understanding and control of defect formation in crystals during self-assembly.

Optical characterization of photonic materials, including fluorescence lifetime enhancement of dyes inside crystalline structures.

Electro-optically active photonic materials with imbibed liquid crystals, e.g. switchable Bragg gratings.

Develop methods to assemble colloids into non-FCC crystals, e.g., CsCl, AB2 or diamond-like crystalline photonic materials. This might be facilitated through biologically inspired approaches by using colloids which are functionalized with appropriate surface groups (DNA oligomers, antigen-antibodies). Other approaches to creating nanostructured microperiodic materials include multibeam holography, two- and multiphoton lithography, and soft-lithography.
