Description

A number of modern technologies are based on the interaction
of atomic species rather than molecules with surfaces. In
particular, atomic hydrogen is involved in chemical processes
like silicon etching and growth or synthetic diamond production.
In this project the interaction of atomic hydrogen with
electronegative coadsorbates (oxygen, sulfur, carbon) and
electropositive coadsorbates (potassium) on metal surfaces
will be inivestigated. We focus on the kinetics and dynamics
of the reaction process. Eley-Rideal and Langmuir-Hinshelwood
reactions will be investigated. The results should be of
technological relevance since they may allow to improve
the procedures applied in surface etching, surface cleaning
and surface modification by atomic species.
