Abstract: | By means of band structure calculations within the density functional
theory and the generalized gradient approximation, we investigate the
electronic structure of self-organized Pt nanowires on the Ge(001) surface.
In particular, we deal with a novel one-dimensional surface state confined
in the nanowire array and clarify its origin. Due to large Pt contributions,
the novel state is rather a mixed Ge–Pt hybrid state than a confined Ge
surface state. Moreover, we compare our results to data from scanning
tunneling microscopy. |
