Theoretical surface physics - Bjørk Hammer¶
Recent research projects by Bjørk Hammer:
We are conducting research within theoretical surface science.
It is important to know and understand the detailed atomic structure
of a surface in order to know the conditions for a chemical reaction
at a surface.
Here the structure of steps in two directions on rutile TiO2 is considered.
See: Steps on rutile TiO:sub:`2`(110): Active sites for water and
methanol dissociation.

Chiral transfer from a chiral modifier to a reacting molecule may
happen if the molecules interact strongly in specific complexes on the
catalyst surfaces.
We study complex formation by varying the intermolecular positions and investigate the nature of the chemical bonds within the complexes.

transfer on a catalyst surface.
