The chemical and physical properties of atomic level surface structure and
dynamics play a crucial role in governing the outcome of many important interfacial
processes such as chemical catalysis, phase separation, interface stability, and
crystal growth. Recently, our attention has been focused on the structure
and dynamics of Self-Assembled Monolayers (SAMs). Alkanethiols on
Au(111) are the beginnings of our forray into the study of organic thin films. We hope to expand our studies
to include polymer thin films and other organic SAMs. Our prior studies
encompass such phenomena as step dynamics, energy exchange and
accomodation, surface diffusion, and adsorbate-surface interactions. These experiments have
been performed using a state-of-the-art helium atom scattering facility at
the University of Chicago's James
Franck Institute.
