The Nanoelectronics and Nanomaterials Group is developing and utilizing a novel powerful suite of experimental and simulation tools for probing biological, nanoelectronic and materials systems down to the atomic level.

Group Leader: Joseph W. Lyding

Research in the Nanoelectronics and Nanomaterials group includes the development of an optical "toolkit" of ultrafast laser systems, interferometric sensors and modulators for medical diagnostics and biological applications, 3-D microscopy, biosensors, and microfluidic BioMEM device analysis. Atomic and molecular level fabrication and characterization is being performed in a unique facility that houses several ultra-high vacuum (UHV) STMs. Techniques have been developed for making atomically precise arrays of molecular and biomolecular species on silicon. Nanoelectronics and Nanomaterials researchers are also using their novel hybrid UHV STM/femtosecond spectroscopy system to explore nanoscale dynamics in semiconductors and molecules, nonlinear spectroscopy, and bond selective chemistry.

The Nanoelectronics and Nanomaterials group has developed sophisticated Monte Carlo and molecular dynamics simulation techniques that are currently being used to study nanoelectronic devices and semiconductor materials. Efforts are now focused on the development of comprehensive self-consistent 3-D modeling of nanostructures, including quantum effects such as single-electron charging effect and the Coulomb blockade. The Nanoelectronics and Nanomaterials group members make extensive use of physical theory, supercomputing resources, and visualization in their modeling work and they maintain the National Center for Computational Electronics in the Beckman Institute, funded mainly by the National Science Foundation.

As part of the Molecular and Electronic Nanostructures research theme, Nanoelectronics and Nanomaterials group members maintain strong collaborations with the 3D Micro- & Nanosystems, Autonomous Materials Systems, Computational Multiscale Nanosystems and the Theoretical and Computational Biophysics groups.
