The emphasis of the research in this program has been to investigate the use of UV lasers for surface diagnostics and for the probing of nanoscale surface physics. Our current program focuses on electron coupling and confinement on nanostructured surfaces, and the use of short-pulse nonlinear laser photoemission techniques to probe these phenomena. Specifically the program is to investigate low-dimensional, quantum confinement of electrons on surfaces patterned with angstrom-scale features. Electronic systems of reduced dimensionality are of interest for a variety of applications for future nano-electronic and magnetic devices. For example, reduced dimensionality plays an important role in such important and timely phenomena as Q bits for quantum computing, and more generally in quantum-dot physics.
