Electron Beam-Induced Writing of Nanoscale Iron Wires on a Functional Metal Oxide
Electron
beam-induced surface activation (EBISA) has been used
to grow wires of iron on rutile TiO<sub>2</sub>(110)-(1 × 1)
in ultrahigh vacuum. The wires have a width down to ∼20 nm
and hence have potential utility as interconnects on this dielectric
substrate. Wire formation was achieved using an electron beam from
a scanning electron microscope to activate the surface, which was
subsequently exposed to FeÂ(CO)<sub>5</sub>. On the basis of scanning
tunneling microscopy and Auger electron spectroscopy measurements,
the activation mechanism involves electron beam-induced surface reduction
and restructuring
