Research Overview:
Our research in experimental surface physics is directed at obtaining a detailed understanding of the fundamental mechanisms involved in dynamical surface processes, in particular laser-induced thermal and photochemical surface processes. We seek to understand the excitation mechanisms and the dynamics of laser-induced desorption, dissociation, and reaction of adsorbed molecules. A powerful way to gain insight into the dynamics uses quantum state resolved, laser spectroscopic detection of desorbed products to determine their final state distributions in the translational, rotational, vibrational, and electronic degrees of freedom. In addition, we are using ultra-short ("femtosecond") laser pulses to probe surface dynamics in real time.
