Research Areas

Integration of Top Down and Bottom Up Nanofabrication

Many interesting nanostructures can arise during epitaxial growth of thin film electronic materials. Self assembly of these nanostructures represents a “bottom up” approach to nanofabrication. At the same time, integration of such nanostructures into devices will require electrical connections, as well as proximal gate electrodes, etc, which are generally made with lithographic techniques: a “top down” fabrication technique. We are particularly interested in nanostructures that are grown in ultra high vacuum (UHV) on atomically pristine substrates. We are developing “top down” nanofabrication techniques that are compatible with the UHV growth methods used to create our nanostructures. Current research in this area is focusing on the ultimate limits of nanostencilling in UHV.

Surface Structure Studies using Scanned Probe Microscopy

Much of our research involves the measurement of atomic surface structure and surface topography using both Scanning Tunneling Microscopy in ultra high vacuum, and atomic force microscopy in air. Many of our past studies on surface atomic structure have yielded insight into the fundamental mechanisms of the growth of metals on silicon surfaces.
