Description
Laser pulses are an intriguing tool for driving non-adiabatic processes at surfaces. Amongst others, they may be utilized for tailoring adsorbed molecules or the surfaces themselves with the aim of custom-made properties that cannot be achieved under equilibrium conditions. We advance the microscopic understanding of the fundamental steps involved in such processes and the details of the dynamics induced by fs-lasers on specific surface sites by a real-space analysis of the resulting products and structures on the sub-nanometer scale, combining short-pulse lasers with scanning tunnelling microscopes. The microscale understanding of the influence of the immediate environment on laser-driven processes, may be used to tailor it for a desired outcome. In this talk, I will present our recent advances in the field.
