These systems include an optical "toolkit" of ultrafast laser systems, interferometric sensors and modulators, and digital data acquisition, control, and processing systems. Applications of these include high-resolution optical imaging 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 housing several ultra-high vacuum (UHV) STMs. Techniques have been developed for making atomically precise arrays of molecular and biomolecular species on silicon. A hybrid UHV STM/femtosecond spectroscopy system has also been developed for studies of nanoscale dynamics in semiconductors and molecules, nonlinear spectroscopy, and bond selective chemistry.
Research projects in the Nanoelectronics area include:
- Atomic scale selective chemistry on silicon surfaces, including the fabrication of precise molecular arrays.
- Nanocharacterization, including the development of STM spectroscopy techniques for atomic scale identification of different chemical species.
- The ambient compatibility of the hydrogen resist process is being utilized to explore potential nanobiotechnology applications in collaboration with other researchers in the Biophotonics area and the Autonomous Materials Systems (AMS), and Computational Electronics (CE) groups.
