Academic Interests and Plans
We are investigating atomic and molecular beam scattering from surfaces prepared under ultrahigh vacuum conditions. The nature of the molecular surface interactions can determine phonon creation/annihilation, electron-hole pair excitation, electron transfer or trapping, and adsorption routes. The major focus of our research efforts involves thermal-energy atomic helium scattering as a technique in the study of clean and adsorbate covered surfaces. Helium is an extremely inert, surface-sensitive, diffractive probe of surface topographies and long range ordering phenomena. We investigate also the dynamics of surfaces,low energy excitations, and surface diffusion processes. Each of these features are of utmost importance in thin film growth at surfaces. In addition we use both diffraction and real-space scanning tunnelling microscopy in in-situ studies of the growth of thin films by both thermal evaporation and chemical vapor deposition.
