The present thesis investigates the electronic and
structural properties of adenine, cytosine, and
guanine layers on hydrogen passivated silicon
(111)(7x7). The (7x7) reconstruction of the silicon
surface was achieved by direct current heating of
the samples in UHV conditions. After in situ
hydrogen passivation layers of the DNA bases were
prepared in different thicknesses by means of
organic molecular beam deposition, all samples
were characterized employing valence band and
core level photoemission spectroscopy. Additionally
the near edge x-ray absorption fine structure of
the DNA base layers was investigated. A detailed and consistent picture of structural and electronic properties of the nucleotide bases in
the solid state could be developed by comparison
of measurements and DFT/B3LYP
calculations.
