Abstract:
We present first theoretical evidence revealing the influence of structural changes on the spin-polarized surface states of
large Co nanoislands grown on
Cu(111). The minority density of electronic states possesses
a pronounced peak whose energetic position depends sensitively on
the Co layers stacking order. Our results suggest a way to deduce
the stacking order of large Co nanoislands using scanning tunnelling
microscopy/spectroscopy.
