Fabricating inorganic-on-organic interfaces for molecular electronics employing a titanium coordination complex and thiophene self-assembled monolayers

摘要

Systems and methods for preparing inorganic-organic interfaces using transition metal coordination complexes and self-assembled monolayers as organic surfaces. In one embodiment, a silicon wafer supports a polycrystalline gold layer, optionally using an intermediate adhesionlayer such as Cr. The surface is reacted with the thiophene end of organic molecular species comprising a thiophene moiety to prepare self assembling monomers (SAMs). The functionalized end of the SAM is then reacted with metal-bearing species such as tetrakis(dimethylamido)titanium, Ti[N(CH₃)₂]₄, (TDMAT) to provide a titanium nitride layer.
