Interaction of Atomic Hydrogen
with Metal Surfaces:
An important topic of our research
group is the adsorption and reaction of atomic hydrogen with
metal surfaces. The understanding of these processes is of fundamental
interest, but it is also relevant for application, e.g. surface etching
in microelectronics, hydrogen storage in metals, new catalytic
reactions, etc. New interaction channels are opened when hydrogen is
used in atomic form, instead of using molecular hydrogen. Some
important issues to be addressed in our group
are summarised in the following:
Investigations of the reaction products
following atomic hydrogen reactions
Translational, vibrational and rotational
state distribution of these products
Eley-Rideal reaction versus
Langmuir-Hinshelwood reactions
Adsorption, absorption and abstraction
probabilities
Angular distribution of reaction products
