abstract = {The electrical properties of alpha,omega-mercaptoalkyl
ferrocenes with different alkyl chain lengths embedded in a
self-assembled host matrix of alkanethiols on Au(111) are
studied by scanning tunneling microscopy and spectroscopy.
Based on current-distance spectroscopy, as well as on the
evaluation of Fowler-Nordheim tunneling current
oscillations, the apparent barrier height of ferrocene is
determined independently by two methods. The electronic
coupling of the ferrocene moiety to the Au(111) substrate is
shown to depend on the length of the alkane-spacer chain. In
a double tunnel junction model our experimental findings are
explained, addressing the role of the different molecular
moieties of the mercaptoalkyl ferrocenes.},
