  We show that thermally evaporated lead (Pb) preserves the electronic
properties of organic monolayers on Si and the surface passivation of the Si
surface itself. The obtained current-voltage characteristics are in accordance
with results from the well-established hanging mercury drop method and preserve
both the molecule-induced dipolar effect and length-attenuation of current. We
rationalize our findings by the lack of interaction between the Pb and the Si
substrate. Our method is fast, scalable, compatible to standard semiconductor
processing, and can help to spur the large-scale utilization of silicon-organic
hybrid electronics.
