Development of an Ultrafast Scanning Tunneling Microscope for Dynamic Surface Studies
Abstract
At the end of three years, we have met the majority of the project goals and made significant progress on the few remaining issues. As outlined in more detail below, we have designed and built a UHV system and incorporated a commercially made, custom designed STM. The microscope has demonstrated atomic resolution. We have a femtosecond laser system, optics for delivering ultrafast laser pulses to the STM, and a computer controlled delay line for time-resolved measurements. This project also has funding from the National Science Foundation, and work continues with that funding while we actively seek additional funds for continued work. We are actively working to develop the instrument as a probe-station for molecular electronics. To that end, we are collaborating with Prof. David Glueck in the Chemistry department on time-domain investigations of Coulomb-blockade effects in Au nanoparticles.
